Adding support for 'adds' and 'removes' in diff content.

Summary:
Does what it says on the label. We already had 'Any changed file content', now we have 'Any added file content' and 'Any removed file content'.
- There is a bit of copied/pasted code here: I'm open to suggestions on how to refactor it so it's less redundant.
- The wording seems a little awkward, and as @epriestley mentioned in T3829, moved code will be detected less than ideally.

Test Plan: Created Herald Rules, verified via dry run that they were triggered in appropriate situations.

Add support for bookmarks in Phabricator emails.

Summary: Right now emails don't include bookmark info (wasn't added in D2897). Lets include it so it's consistent with the web UI.

Test Plan: Inspected code, made sure it matched web UI code. Verified that web UI with these changes was consistent with rendering before refactoring.

Prevent administrators from locking themselves out of applications

Summary: Ref T603. This could be a nicer UX, but limit the amount of foot-shooting that users can possibly do. You can still manage if you're really tricky ("Members of project X", then leave the project) but this should make it hard to make a mistake. It seems very unlikely any user ever intends to lock themselves out of an application.

Test Plan: Set an application's view policy to permissive ("Administrators") and nonpermissive ("No One") values. The former were accepted, the latter rejected.

Tighten up some policy interactions in Herald

Summary:
Ref T603. Herald is a bit of a policy minefield right now, although I think pretty much everything has straightforward solutions. This change:

  - Introduces "create" and "create global" permisions for Herald.
    - Maybe "create" is sort of redundant since there's no reason to have access to the application if not creating rules, but I think this won't be the case for most applications, so having an explicit "create" permission is more consistent.
  - Add some application policy helper functions.
  - Improve rendering a bit -- I think we probably need to build some `PolicyType` class, similar to `PHIDType`, to really get this right.
  - Don't let users who can't use application X create Herald rules for application X.
  - Remove Maniphest/Pholio rules when those applications are not installed.

Test Plan:
  - Restricted access to Maniphest and uninstalled Pholio.
  - Verified Pholio rules no longer appear for anyone.
  - Verified Maniphest ruls no longer appear for restricted users.
  - Verified users without CREATE_GLOBAL can not create global ruls.

Modernize "Test Console" and fix a minor display bug with "Always"

Summary:
  - Use the box view in the test console.
  - Let the test console load tasks and mocks. We should move this to the adapters (`canAdaptObject($object)` or something).
  - Fix a minor issue with "Always": hiding the whole cell could make the table layout weird in Safari, at least. Just hide the select instead.

Test Plan:
  - Used test console on task.
  - Used test console on mock.
  - Created (silly) rule with "Always" and also some other conditions.

Make Herald transcripts policy-aware

Summary:
Ref T603. Herald transcripts potentially leak a bunch of content (task text, revision/commit content). Don't let users see them if they can't see the actual objects.

This is a little messy but ends up mostly reasonable-ish.

Test Plan:
  - Verified that transcripts for objects I couldn't see no longer appear in the list, and reject access.
  - Verified that transcripts for objects in applications I can't see reject access, albeit less gracefully.

lipsum - tighten up some test data generation

Summary:
maniphest tasks were fataling with priority 0 before making sure to add the return null if new object trick to the maniphest pro editor.

pholio had a problem where if you had no jpegs you were walking off array_rand. tighten the math and then just return a built-in if no uploaded user images could be found. Fixes T3889.

Test Plan: bin/lipsum generate for a few minutes and no errors

Stop using loadRelationships in differential related herald adapters

Summary:
Used `DifferentialRevisionQuery` with the relevant `need*()` calls in the test controller.
And started assuming the revision has reviewers and CC phids in `HeraldDifferentialRevisionAdapter`.

Test Plan:
Added herald rules that use revisions (one for revisions another for commit) and reviewers.
Created, accepted and landed a revision that matched the rules and checked all rules were applied.
