Add loadObject() methods to PhabricatorObjectMailReceiver subclasses

Summary: This doesn't do anything, but touches a bunch of files so I split it out to reduce the size of the next diff. Basically, make `MailReceiver` classes responsible for loading their application objects. Ref T1205.

Test Plan: Inspection / next diff / code is not reached.

Move sender validation into MailReceiver classes

Summary:
Ref T1205. Finally able to delete a big chunk of this nastiness.

Make MailReceivers responsible for validating senders. For object creation receivers (bugs, conpherences) this just means that users must not be disabled. For other receivers the senders must be able to see the objects, have the right hashes, etc., according to policy.

Test Plan: Added a bunch of test cases (everything except policy). Verified behavior via the Receive test console.

Make "Receive Test" mail form use MailReceivers

Summary: Currently this is fairly hard-coded. Instead, make it use available receivers. Ref T1205.

Test Plan: Used mail form to send mail to various objects (Dnn, Tnn, Cnn, etc.). Only some of these work right now because the receiver thing still hard-codes a bunch of junk.

Rename `bin/files metadata` to `bin/files rebuild` and let it rebuild MIME information

Summary:
See <https://github.com/facebook/phabricator/issues/320>. Files can end up with a bad MIME type, and we don't update it when uploading another copy of the file since obviously the new copy has the same data and thus the same MIME type.

  - Rename `bin/files metadata` to `bin/files rebuild` to make it a more consistent verb.
  - Let it rebuild MIME types so users who hit issues like this can run `bin/files rebuild --all --rebuild-mime` to straighten things out.

Test Plan: Ran `bin/files` in various modes, examined output.

Add a setup warning about missing 'fileinfo'

Summary:
See <https://github.com/facebook/phabricator/issues/320>. We have a soft dependency on 'fileinfo', which we try to recover from (with `file`) but won't be able to on Windows and apparently FreeBSD systems. Since users can ignore setup checks anyway now, just raise a warning during install.

I believe almost all installs should have this extension, it has been part of the core for a long time.

Test Plan: Faked setup failure, looked at warning. "Solved" setup failure, saw it go away.

Remove the last hardcoding from PhabricatorMetaMTAReceivedMail

Summary:
Moves all remaining mail handling into ReplyHandlers.

Farewell, `getPhabricatorToInformation()`! You were a bad method and no one liked you.

Ref T1205.

Test Plan:
  - Used test console to send mail to Revisions, Tasks, Conpherences and Commits (these all actually work).
  - Used test console to send mail to Requests, Macros, Questions and Mocks (these accept the mail but don't do anything with it, but didn't do anything before either).

Diffusion - move querying for stable commit name to occur over conduit

Summary: Ref T2784. This is a lower-level one from drequest so it gets the conditional initialization treatment. Consolidated SVN as well even though SVN is issuing database queries; I felt better about the code de-duplication despite the small performance hit when we could just query the DB directly in the SVN case.

Test Plan: browsed around my Phabricator repositories in Mercurial, Git, and SVN flavors. Looked good.

Implement #yoloswag

Summary:
Ref T3190. #shipit

Likely future work:

  - Extract project mentions from remarkup for ApplicationTransactions; this isn't relevant in any apps right now (but will be in Pholio before tooo long). Ref T3189.
  - Allow projects to have alternate short names. As written, this is fine for most projects ("Differential" is `#differential`) but not so great for other projects ("Phabricator Public & Media Relations" is `#phabricator_public_media_relations`). This also breaks refs when you rename a project. Better would be letting long project names have short aliases (`#pr`) as permitted alternatives.

Since this mention uses `#` instead of a letter, I needed to do a small amount of regexp gymnastics.

Test Plan:
you only #yolo once
