Use subtler highlighting for copied and moved code

Summary:
The highlighting is distracting according to Nick Shrock and others.
Real designer, Lee Byron, helped me with this.

It also gives us unagressive target for jumping to the source line in future.

Another feature I will probably implement is highlighting also the source of copies/moves.
I will use the right side of the left column for it.

Test Plan:
Hover copied notifier.
Hover coverage notifier.

I've also checked that this doesn't break our super-flaky old/new code JavaScript detector.

Support branch offset/limit in Mercurial

Summary:
  - Support offset/limit as added by D2442, for Mercurial.
  - We just list everything and slice, no clear way to do better and this isn't a major perf issue.
  - No clear way to easily get by-update sorting, we can implement this by looking up revs if someone asks.
  - Bury some of the Git implementation details inside the Git query.

Test Plan:
  - Looked at a Git repo, clicked "View All Branches".
  - Looked at a Hg repo, clicked "View All Branches".
  - Limited page size to 1, made sure it limited properly.

Add a setting to blanket-disable autoclosing revisions in a repository

Summary: For git workflows where developers push personal feature branches to the origin, this is a quick workaround until T1210 is implemented properly. I'll also mention this in D2446.

Test Plan:
  - Committed a revision in an "autoclose" repository; it was autoclosed. Committed a revision in a no-autoclose repository, it was not autoclosed.
  - Edited repositories, saving the "autoclose" setting as enabled/disabled.
