Summary:
Currently, we sort all results alphabetically. This isn't ideal. Instead, sort them like this:
- If the viewing user appears in the list, always sort them first. This is common in a lot of contexts and some "Ben Evans" guy is sorting first on secure.phabricator.com and causing me no end of aggravation.
- If the tokens match a "priority" component (e.g., username), sort that before results which do not have a "priority" match.
- Within a group (self, priority, everything else) sort tokens alphabetically.
NOTE: I need to go add setUser() to all the tokenizers to make the "self" rule work, but that's trivial so I figured I'd get this out first.

Previously, "aaaaaepriestley" (first alphabetic match) would sort before "epriestley" (the viewing user). Now, "epriestley" sorts first because that is the viewer.

Summary:
See T730 and the slightly-less-pretty version of this in D1398.
When a user takes an action in Differential that has no effect (for instance,
accepting an already-accepted revision), prompt them:
Action Has No Effect
You can not accept this revision because it has already been accepted.
Do you want to post the feedback anyway, as a normal comment?
[Cancel] [Post as Comment]
If they have no comment text, the dialog only says "Cancel".
I think this is probably the best way to balance all the concerns here -- it
might occasionally be a little annoying, but that should be rare, and it should
never be confusing (the current workflow is extremely confusing).
This also fixes the issue where you can add all sorts of CCs who are already
part of the revision, either explicitly or via mentions.

Posted some has-effect and has-no-effect comments, made different

Summary:
We don't currently validate CSRF tokens on this workflow. This allows an
attacker to upload arbitrary files on the user's behalf. Although I believe the
tight list of servable mime-types means that's more or less the end of the
attack, this is still a vulnerability.
In the long term, the right solution is probably to pass CSRF tokens on all Ajax
requests in an HTTP header (or just a GET param) or something like that.
However, this endpoint is unique and this is the quickest and most direct way to
close the hole.
Test Plan:
- Drop-uploaded files to Files, Maniphest, Phriction and Differential.
- Modified CSRF vaidator to use __csrf__.'x' and verified uploads and form

The goal here is to have the cell choose a size naturally and for its content to
render with "overflow: hidden" if the natural size isn't large enough to contain
the content. "white-space: pre" or "white-space: nowrap" would prevent wrapping
but potentially make the table exceed the display width when a better behavior
is to hide some of the commit message.
Also use utf8-aware shortening, now that we have a function for it.
Casting a wide net in case anyone has a better way to do the CSS here. It's kind

Summary:
We currently cycle CSRF tokens every hour and check for the last two valid ones.
This means that a form could go stale in as little as an hour, and is certainly
stale after two.
When a stale form is submitted, you basically get a terrible heisen-state where
some of your data might persist if you're lucky but more likely it all just
vanishes. The .js file below outlines some more details.
This is a pretty terrible UX and we don't need to be as conservative about CSRF
validation as we're being. Remedy this problem by:
- Accepting the last 6 CSRF tokens instead of the last 1 (i.e., pages are
valid for at least 6 hours, and for as long as 7).
- Using JS to refresh the CSRF token every 55 minutes (i.e., pages connected
to the internet are valid indefinitely).
- Showing the user an explicit message about what went wrong when CSRF
validation fails so the experience is less bewildering.
They should now only be able to submit with a bad CSRF token if:
- They load a page, disconnect from the internet for 7 hours, reconnect, and
submit the form within 55 minutes; or
- They are actually the victim of a CSRF attack.
We could eventually fix the first one by tracking reconnects, which might be
"free" once the notification server gets built. It will probably never be an
issue in practice.
Test Plan:
- Reduced CSRF cycle frequency to 2 seconds, submitted a form after 15
seconds, got the CSRF exception.
- Reduced csrf-refresh cycle frequency to 3 seconds, submitted a form after 15
seconds, got a clean form post.
- Added debugging code the the csrf refresh to make sure it was doing sensible
things (pulling different tokens, finding all the inputs).
