4596e3876b Improve scrolling behavior for lightboxes in Safari
Summary: Our "html { overflow-y: scroll; }" makes Safari flip out when we put "hidden" on body. Instead, put the scroll on `body` and then replace it with `hidden` when the lightbox is visible.

Test Plan: In Safari, the body scrollbar vanishes when the lightbox is active and scrolling no longer causes spasms.

0c48c1f487 Make date control include times
Summary:
See discussion in T404. Basically, the problem with date-only controls is that they may behave unpredictably in the presence of timezones. When you say "This needs to be done by Oct 23", you probably mean "Oct 23 5PM PST" or something like that, but someone in China may see the "Oct 24" and hit the deadline in good faith but be 10 hours too late. T404 has more discussion and examples. There are ways to fake this, but they get more complicated if the guy in China needs to move the date forward 24 hours.

I think the best solution to this is to not have date-only controls, and always display the time. This makes it absolutley unambiguous what something means, because the guy in the US will set "Oct 23 5PM" and the guy in China will see that accurately in local time.

The downside is that it's slightly more visual clutter and work for the user to specify things precisely, but I added some hints (start/end of day, start/end of business) that will hopefully let us pick the right default in most cases.

Test Plan:
Set some dates.

{F21956}

This has a couple of edge case issues on resize and some not-so-edge-case issues on mobile, but should be good to build T407 on without API changes.

D3707 removed some overbroad rules for when we trigger workflows, but there is still one case we should check for -- an <a /> without workflow inside a <form /> with workflow. This occurs in, e.g., the "help" button in Remarkup.

If the node with workflow isn't a link, don't trigger workflow. This should allow the <a><img /></a> case to keep working properly.

Cleans up some of the mess I made in D3694. Basically:

  - Blogs now have a separate "live" view that we use to handle domains / skins.
  - Simplified some views and use IDs in some URLs for consistency.

Summary:
introduce an abstract "PhameBlogSkin" class and instantiate two versions -- PhabricatorBlogSkin (Default) and PhacilityBlogSkin.

Most notable hack is including the directory /rsrc/images/phacility - this lets things "work" without messing around with the phacility.com CSS and instead just cutting and pasting most of the file.

Test Plan: played around with Phame a bunch. In particular, created a blog with a custom domain and the phacility skin. Verified it looked good and individual posts looked okay.

e00d3b72fe Improve the implementation of Notifications
Summary:
Currently, you can't change a notification that's already shown. There's no reason for this.

(I'm planning to put file upload progress/errors in notifications.)

  - Make `setContent()` and `setDuration()` immediately affect the notification.
  - When there are more than 5 notifications, queue them up instead of dropping them.
  - Allow arbitrarily many classes to be added/removed.
  - Make the examples in the UIExamples tests more rich.

Test Plan:
  - Verified normal notifications continue to function as expected.
  - Played with the UIExamples notifications:
    - Verified the "update every second" notification udpated every second.
    - Verified the permanent alert notification was yellow and requires a click to dismiss.
    - Verified the interactive notification responds correctly to "OK" / "Cancel".
    - Verified the "click every 2 seconds" notification doesn't vanish until not clicked for 2 seconds.

5b74b8b765 Add basic "Subscriptions" application
Summary:
Basic infrastructure for generalizing subscriptions/CCs for T1808, T1514 and T1663.

  - Implement `PhabricatorSubscribableInterface` and you'll get a subscribe/unsubscribe button for free.
  - If there are any auto-subscribed users (like the question author) you can specify them; this makes more sense for Tasks and Revisions than Ponder probably, but maybe the author should be auto-subscribed.
  - Subscriptions are either "explicit" (the user clicked 'subscribe') or "implicit" (the user did something which causes them to become subscribed naturally). If a user unsubscribes, they'll no longer be added by implicit subscriptions. This may or may not be relevant to Ponder but is an existing Herald feature in Differential.
  - Helper method on PhabricatorSubscribersQuery to load subscribers.
  - This doesn't handle actually sending email, etc. I think that's all so application-specific that it doesn't belong here.
  - Now seems to work.

3df0cfa641 Autoscroll sidebar
Summary:
If the ToC in sidebar is long then the active file can be under the fold when we highlight it.

This also saves some CPU cycles because it highlights only after scrolling of the main window and not in the elements.

Test Plan:
Scrolled on a long diff.
Scrolled the ToC.

8481f7ef09 Don't open symbols on double click
Summary:
My average double click speed is 10 ms but I tried to double click as I think normal people double clicks and it was around 200 ms.
I don't want to make the timeout much longer because it looks like that something doesn't work.

Test Plan:
Double clicked on symbol.
Clicked on symbol.

5978bbfc64 Do sampled profiling of requests
Summary:
People have occasionally complained about phabricator being slow. We have
the access log to look at to see when slowness happens, but it doesn't tell
us much about why it happened. Since it's usually a sporadic issue that's
reported, it's hard to reproduce and then profile. This change will allow us
to collect sampled profiles so we can look at them when slowness occurs.

Test Plan:
checking that sampling works correctly:
- set rate to 0; do several page loads; check no new entries in table
- set rate to 1; check that there's a new row in the table for each page load
- set rate to 10; check that some requests write to table and some don't
check new ui for samples:
- load /xhprof/list/all/, see a list with a lot of samples
- load /xhprof/list/sampled/, see only sampled runs
- load /xhprof/list/manual/, see only non-sampled runs
- load /xhprof/list/my-runs/, se only my manual runs
