Remove PhabricatorFeedStoryManiphest and ManiphestAction

Summary:
I'll hold this for a couple weeks.

These classes are now only used to render legacy feed stories. I don't plan to migrate the stories since I don't think they're particularly valuable, and migrating them would be complex and time consuming.

With these classes removed, legacy Maniphest feed stories simply vanish from feed.

Test Plan: `grep`, viewed feed, verified it worked but omitted old-style stories.

Clean up some ordering and strata edge cases in Phrequent

Summary:
Ref T3569. Two issues:

  # Since `sort()` is not stable, instantaneous events (ending on the same second they start) would sometime sort wrong and produce the wrong results. Guarantee they sort correctly.
  # Because events can end at any time, there are some additional special cases the algorithm didn't handle properly. Draw a bunch of ASCII art diagrams so these cases work properly.

Test Plan:
  - No more fatal when tracking an object for the first time.
  - Unit tests.

Clean up supplemental capabilitiy checks in transaction edits

Summary:
We have this commented-out chunk of code now which was originally buggy and is now just nonfunctional.

For now, the core edit types don't always require CAN_EDIT (e.g., subscribe, comment, add edges), except for editing the edit policy itself, which always does. Add a supplemental capability check there and let everything else go through with CAN_VIEW. We can buff the policy checks on application editors over time, they all require appropriate capabilities to get to in the first place anyway.

Test Plan: Created and edited some tasks without getting overwhelmed with policy exceptions.

Fix "Manage herald rules" link by removing it

Summary: Fixes T4001. I broke this some time ago and no one has complained. I don't think it gets much use, and we haven't added it for the newer apps. Just get rid of it rather than adapt the URIs for ApplicationSearch.

Test Plan: Unit tests, sent myself some email.

Add capabilities for editing task triage details (priority, assignee, etc)

Summary:
This is primarily a client request, and a little bit use-case specific, but policies seem to be holding up well and I'm getting more comfortable about maintaining this. Much if it can run through ApplicationTransactions.

Allow the ability to edit status, policies, priorities, assignees and projects of a task to be restricted to some subset of users. Also allow bulk edit to be locked. This affects the editor itself and the edit, view and list interfaces.

Test Plan: As a restricted user, created, edited and commented on tasks. Tried to drag them around.

Stop writes to the old Relationship table

Summary: Ref T1279. The new stuff seems stable, so stop writes to the old tables.

Test Plan:
  - Added and removed reviewers.
  - Grepped for `::RELATIONSHIP_TABLE` to verify we really have no more reads.
  - Grepped for `::RELATION_REVIEWER`.

Tie application event listeners to the applications they listen for

Summary:
Ref T3675. Some of these listeners shouldn't do their thing if the viewer doesn't have access to an application (for example, users without access to Differential should not be able to "Edit Tasks"). Set the stage for that:

  - Introduce `PhabricatorEventListener`, which has an application.
  - Populate this for event listeners installed by applications.
  - Rename the "PeopleMenu" listeners to "ActionMenu" listeners, which better describes their modern behavior.

This doesn't actually change any behaviors.

Test Plan: Viewed Maniphest, Differntial, People.

Make event-triggered actions more aware of application access

Summary:
Fixes T3675.

  - Maniphest had a couple of old non-event listeners; move them to events.
  - Make most of the similar listeners a little more similar.
  - Add checks for access to the application.

Test Plan:
  - Viewed profile, project, task, revision.
  - Clicked all the actions.
  - Blocked access to various applications and verified the actions vanished.

Reduce surface area of DifferentialComment API

Summary:
Ref T2222. Shrink the API to make it easier to move this object's storage to ApplicationTransactions.

Fixes T3415. This moves the "Summary" and "Test Plan" into the property list, and thereby fixes all the attribution problems associated with commandeering, creating a revision from another user's diff, etc.

Test Plan: Browsed several revisions.

Lock policy queries to their applications

Summary:
While we mostly have reasonable effective object accessibility when you lock a user out of an application, it's primarily enforced at the controller level. Users can still, e.g., load the handles of objects they can't actually see. Instead, lock the queries to the applications so that you can, e.g., never load a revision if you don't have access to Differential.

This has several parts:

  - For PolicyAware queries, provide an application class name method.
  - If the query specifies a class name and the user doesn't have permission to use it, fail the entire query unconditionally.
  - For handles, simplify query construction and count all the PHIDs as "restricted" so we get a UI full of "restricted" instead of "unknown" handles.

Test Plan:
  - Added a unit test to verify I got all the class names right.
  - Browsed around, logged in/out as a normal user with public policies on and off.
  - Browsed around, logged in/out as a restricted user with public policies on and off. With restrictions, saw all traces of restricted apps removed or restricted.

Add a secret board view to Projects

Summary:
Ref T1344. This is //very// rough. Some UI issues:

  - Empty states for the board and columns are junky.
  - Column widths are crazy. I think we need to set them to fixed-width, since we may have an arbitrarily large number of columns?
  - I don't think we have the header UI elements in M10 yet and that mock is pretty old, so I sort of very roughly approximated it.
  - What should we do when you click a task title? Popping the whole task in a dialog is possible but needs a bunch of work to actually work. Might need to build "sheets" or something.
  - Icons are slightly clipped for some reason.
  - All the backend stuff is totally faked.

Generally, my plan is just to use these to implement all of T390. Specifically:

  - "Kanban" projects will have "Backlog" on the left. You'll drag them toward the right as you make progress.
  - "Milestone" projects will have "No Milestone" on the left, then "Milestone 9", "Milestone 8", etc.
  - "Sprint" projects will have "Backlog" on the left, then "Sprint 31", "Sprint 30", etc.

So all of these things end up being pretty much exactly the same, with some minor text changes and new columns showing up on the left vs the right or whatever.

Test Plan: See screenshot.
