Restore some missing features from Maniphest mail

Summary:
Ref T2217. Fixes two issues:

  # The "task created" email didn't include the task description, but should.
  # We were treaging the "status" event as the "create", but that's kind of a mess. Treat the "title" event as the "create" instead. This makes initial emails say "[Created]".

Test Plan: Created some tasks, got better emails.

Remove a bunch of reundant checks for transactions with no effect from Maniphest

Summary: Ref T2217. These checks are no longer necessary, ApplicationTransactions handle them for us.

Test Plan:
  - Made a no-effect edit, verified no new transactions showed up.
  - Made real edits, saw them happen and leave transactions.
  - Made an edit which just reorders CCs, saw it detected as no-effect.
  - As above, with projects.

Allow draggable elements to be dragged to the first list position

Summary:
Currently, draggable lists (in Config and ApplicationSearch, for example) don't let you drag an item into the first position.

This is because the behavior is correct in Maniphest: the first position is above an initial header, like "High Prioirty", and shouldn't be targetable.

Permit the behavior in general; forbid it in Maniphest.

Test Plan:
  - Dragged elements into the first position in ApplicationSearch.
  - Failed to drag elements into the first position in Maniphest.

Use ManiphestTaskQuery in nearly all interfaces

Summary:
Ref T603. Make almost every task read policy-aware. Notable exceptions are:

  - Edge editor -- this stuff is prescreened and should be moved to ApplicationTransactions eventually anyway.
  - Search/attach stuff -- this stuff needs some general work. The actual list should be fine since you can't pull handles. There may be a very indirect hole here where you could attach an object you can't see (but do know the ID of) to an object you can see. Pretty fluff.
  - The "Tasks" field in Differential will let you reference objects you can't see. Possibly this is desirable, in the case of commandeering revisions. Mostly, it was inconvenient to get a viewer (I think).

Test Plan:
  - Called `maniphest.info`.
  - Called `maniphest.update`.
  - Batch edited tasks.
  - Dragged and dropped tasks to change subpriority.
  - Subscribed and unsubscribed from a task.
  - Edited a task.
  - Created a task.
  - Created a task with a parent.
  - Created a task with a template.
  - Previewed a task update.
  - Commented on a task.
  - Added a dependency.
  - Searched for "T33" in object search dialog.
  - Created a branch "T33", ran `arc diff`, verified link.
  - Pushed a commit with "Fixes T33", verified close.

Remove obsolete code from ManiphestTaskQuery

Summary:
Ref T603. Cleans up some obsolete stuff here:

  - We no longer ever query by min/max priority (instead, `withPriorities(...)`).
  - A parent class provides limit/offset.
  - Result count is no longer reliable with policies. We could do "about X tasks" or something, but just drop it for now. There's only one remaining callsite anyway.

Test Plan:
  - `grep`
  - Viewed task list.
  - Viewed a project page.
