Summary:
- For images that aren't too large to fit, keep the stage at about 85% of the viewport height. This prevents it from bouncing around as you switch between images, and generally makes it feel big and important like it should. When the stage is larger than images, we center them vertically.
- As the viewport is resized, shrink the stage and, if necessary, the images on it.

Summary:
Currently, if an image is too wide for the viewport, we freak out. Instead, scale it down.
This means we must also scale down all the rectangles on it, which is why this is tricky. However, all the draw/load separation has made it reasonably straightforward.
We'll possibly need to add some kind of "view full size" thing. I'm planning to add an element which shows "85%" or whatever if it's currently scaled.

Summary:
Currently, we issue one Ajax request to get inline comments, and then draw them when they come back. This has some limitations:
- A user could quickly click image 1, and then click image 2. The request for image 1 may take longer to come back than image 2. In this case, we'd draw the image 2 inlines and then draw the image 1 inlines when that request arrived, resulting in image 2 shown with both image 1 and image 2 comments. This is hard to make happen in a sandbox because the requests are so fast, but prevent it by drawing only the currently visible image's inlines.
- Every time we want to draw inlines, we need to request them -- even if we've already loaded them! This allows us to draw them without reloading them (although we don't actually do this, yet). When we do, it will make it faster to switch between images you've aleady looked at (and we can do other optimizations).
Test Plan: Clicked between images, saw inlines draw correctly. Added a new inline. Moused over inlines.

- When the page first loads, we draw the image on the server with PHP.
- When the user clicks a thumbnail, we draw the image on the client with JS.
Since we can't reasonably get rid of the client version of this, move it all to the client. This paves the way for some future features, like:
- Doing some magic with stage sizing
- URIs that jump to a specific comment
- showing "loading" indicators while images are loading

I attempted to test every interface. I probably missed some stuff, but I at least have some level of confidence that the `phutil_tag` branch is fairly stable.
Fixed these issues:
[1] Fixed a Herald issue with object links in transcripts. Some actions return
links; this was previously hard-coded.
[2] DarkConsole refactoring created an issue where the "`" event handler registered too many times.
[3] Fixed a bug where `strlen($value)` was being checked, but fields may now return array(). Possibly we should implement phutil_is_empty_html() or similar.
[4] Fixed a undefined variable issue for image edit transactions.
[5] Fixed an issue with rendering participant transactions. This required phutil_safe_html() because `pht()` can't handle `array()` for `%s`.
[6] Fixed an issue where feed was entirely overescaped by reverting an overly ambitious render_tag -> tag.
[7] Fixed an issue with strict tables and inserting `''` instead of `0` into an integer column.
[8] Fixed an issue where • was shown escaped.
[9] Fixed an issue where "no data" was overescaped.
[10] Fixed an issue with strict tables and inserting `''` instead of `0` into an integer column.
[11] Fixed an issue with strict tables and inserting `''`.
[12] Fixed an issue with missing space after ":" for mini panels.
Encountered (but did not fix) these issues:
[X1] "e" works incorrectly on comments you are not allowed to edit. Did not fix.
[X2] Coverage currently interacts incorrectly with "--everything" for Phutil tests.

Notably, this improves the use case of taking a known action on a diff. Currently, you have to wait for everything to load or the comments keep getting scrolled down. After this change, the comments stay in the same place on screen.

- Reloaded it while scrolled at the top; normal behavior (no scrolling).
- Reloaded it, scrolled to the bottom. Comment area now stable.
- Reloaded it, kind of scrolled around the middle? Behavior seemed stable/reasonable. This one is kind of heursitic so it's hard to say I'm getting it totally right or not, but it's less important than the "bottom" case.

This accomplishes three major goals:
# Fixes phutil_render_tag -> phutil_tag callsites in DarkConsole.
# Moves the Ajax request log to a new panel on the left. This panel (and the tabs panel) get scrollbars when they get large, instead of making the page constantly scroll down.
# Loads the panel content over ajax, instead of dumping it into the page body / ajax response body. I've been planning to do this for about 3 years, which is why the plugins are architected the way they are. This should make debugging easier by making response bodies not be 50%+ darkconsole stuff.
Additionally, load the plugins dynamically (the old method predates library maps and PhutilSymbolLoader).

Summary:
I broke this a bit a few revisions ago by making `phabricator_render_csrf_magic()` return array instead of string without actually grepping for callsites.
Instead of building a form in JS, build it in PHP and just change its action in JS. This is simpler and doesn't require us to expose CSRF magic in more places.
This change triggered a rather subtle bug: if we rendered a normal form on the page (and thus installed the "disable forms when submitted" behavior), the download button would incorrectly disable after being clicked. This doesn't currently happen in Files because we don't put a form on the same page as the download button.
Instead, make the "disable" behavior check if the form is downloading stuff, and not disable stuff if it is. Then mark the lightbox and Files form as both download forms.
Test Plan: Used lightbox; used Files. Verified download buttons download the right stuff and behave correctly. Grepped for other download forms, but all the other places where we write "download" don't appear to actually be download links.

Fixes T181. I actually have no idea what the original issue in T181 was, but this fixes several problems:
- The code for figuring out whitespace-only changes was extremely confusing and probably buggy (the code for figuring out unchanged files was equally confusing but probably less buggy).
- When rendering a whitespace shield, we did not offer a "Show Changes" link. Instead, show the "Show Changes" link: we can always render the content beneath this link.
- When clicking "Show Changes", we used the current whitespace mode, which might result in a diff with no changes. Instead, force "show all" whitespace mode.
- We never offered a "show changes" link for unchanged files. Instead, offer this link if we can service it.
- When clicking "Show Changes", we pierced the shield but didn't force file content, which would fold the entire file even if it was available. Instead, force the file content.
Test Plan: Generated whitespace-only and no-change diffs. Clicked shield links, or verified no shield link available in no-change-with-no-content. Generated an "@generated" change, verified shield worked correctly.
