Actually (???) fix mail multiplexing. I am awful at programming.
Fix patch 131 for db with lots of revisions

Summary:
The old version of this loads all differential revisions at once, but that much
can't all be loaded into memory when there are close to 500,000 revisions. This
diff splits up loading the revisions.

Test Plan: Ran this to run the migration in our install

Use "user-select: none" to provide a visual cue about copy/paste JS magic

Summary:
  - For line numbers, use "user-select: none" to make them unselectable. This provides a stronger visual cue that copy/paste is enchanted.
  - In Paste, make it look sensible again after the blame-on-blame refactor in Diffusion. See also TODO to share this code formally.
  - In Diffusion, use the "phabricator-oncopy" behavior.

NOTE: I left blame/commit columns selectable in Diffusion, since you might reasonably want to copy/paste them?

NOTE: In Differential, the left side of the diff still highlights, even though it will be copied only if you select part of a line on the left and nothing else. But this seemed like a reasonable behavior, so I left it.

Test Plan:
  - Looked at Paste. Saw a nice line number column. Selected text, got the expected selection. Copied text, got the expected copy.
  - Looked at Diffusion. Saw a nice line number column, still. Selected text, got expected selection. Copied text, got expected copy.
  - Looked at Differential. Highlighted stuff, got expected results. Copied stuff, got expected results.

New maniphest event TYPE_MANIPHEST_DIDEDITTASK

Summary:
This event is fired after a task is created and assigned with an id.
Use case is sending an email notification to everyone in a project when a new task is
submitted to said project.

Test Plan:
Implement the event listener, submit a new task to a project, see if the project members
receive an email notification. I will submit the event handler in a separate diff once it's a bit
prettier and tested more thoroughly.

Allow revisions to be commandeered

Summary:
  - Adds "Commandeer Revision", to allow you to plunder revisions from those lost to sea (e.g., interns who have left or co-workers who are dealing with a family emergency).
  - Removes admin-abandon to simplify things, since you can just Commandeer + Abandon now.
  - There are other workarounds available but this is the natural/expected workflow (and the one everyone always asks for) and there's no real reason not to allow it.

Test Plan: Swashbuckled.
