Summary:
Allow duplicate tasks to be selected and merged in Maniphest.
I didn't create a separate transaction type for this because that implies a
bunch of really complicated rules which I don't want to sort out right now
(e.g., do we need to do cycle detection for merges? If so, what do we do when we
detect a cycle?) since I think it's unnecessary to get right for the initial
implementation (my Tasks merge implementation was similar to this and worked
quite well) and if/when we eventually need the metadata to be available in a
computer-readable form that need should inform the implementation.
Plenty of room for improvement here, of course.
Test Plan:
Merged duplicate tasks, tried to perform invalid merge operations (e.g., merge a
task into itself).
Tested existing attach workflows (task -> revision, revision -> task).

Summary:
You can currently attach tasks to revisions from Differential, but not revisions
to tasks from Maniphest. Allow editing from either side.
This logic is kind of tricky but the alternative was massive code duplication.
Test Plan:
Added and removed revisions from maniphest. Added and removed tasks from
differential.
This should have no impact on the Facebook install since none of this is used
there.
