Migrate project membership to edges

Summary:
  - Store project members in edges.
  - Migrate existing members to edge storage.
  - Delete PhabricatorProjectAffiliation.
  - I left the actual underlying data around just in case something goes wrong; we can delete it evenutally.

Test Plan:
  - Ran migration.
  - Created a new project.
  - Joined and left a project.
  - Added and removed project members.
  - Manually called PhabricatorOwnersOwner::loadAffiliatedUserPHIDs() to verify its behavior.

Fancier tooltips for revision lists

Summary:
Put flag note in a Javelin tooltip on the flag, and extra
reviewers in a Javelin tooltip on the (+N). This is a bit more expensive
because we have to fetch all of their usernames but I'm hoping that's
okay?

Test Plan:
Load a bunch of revision lists. Mouse on. Mouse off. Mouse
on. Mouse off.

Fix "show raw file" showing wrong file

Summary:
In a revision with multiple diffs like
https://secure.phabricator.com/D3168?vs=6094&id=6095
clicking "Show Raw File (Left)" while comparing diffs 1 and 2 brings up
the version from base, instead of from diff 1. This is because the hunks
are stored as diffs between base and diff X, and the raw file is
generated from the hunks. This introduces a hack which is probably not
actually correct but seems to work for the 90% case.

(The "Show Raw File (Right)" button was and remains correct.)

Test Plan: Click raw file buttons while comparing different diffs.

Fix sorting algorithm for group-by-project

Summary:
When viewing Maniphest tasks grouped by project, there's this
weird algorithm that involves generating strings to use as sort keys.
It's pretty clearly wrong in several cases; this aims to fix it.

Test Plan:
Open Maniphest and try to sort by things. Unfortunately, I
don't have access to a decent Maniphest database, so I'm not certain it
works as it should.

Allow commits to be associated with projects and associated goodies

Summary:
- Commit detail view
 - List of projects
 - "edit" action which takes the user to a simple form where they can only add / remove projects.
-  Integrated the project relationship into the commit search indexer
 - fixed a bug from D790; it seems you must select the column if you're going to join against it later. Without this change searching for author or projectfails 100% for me.

Test Plan: added and removed projects. verified appropriate projects showed up in detail and edit view. searched for commits by project and found the ones I was supposed to...!
