epriestley ae7488f710 Drive commit message rendering from field specifications
Summary:
When rendering commit messages, drive all the logic through field specification
classes instead of the hard-coded DifferentialCommitMessageData class. This
removes DifferentialCommitMessageData and support classes.

Note that this effectively reverts D546, and will cause a minor break for
Facebook (Task IDs will no longer render in commit messages generated by "arc
amend", and will not be editable via "arc diff --edit"). This can be resolved by
implementing the feature as a custom field. While I've been able to preserve the
task ID functionality elsewhere, I felt this implementation was too complex to
reasonably leave hooks for, and the break is pretty minor.

Test Plan:
  - Made numerous calls to differential.getcommitmessage across many diffs in
various states, with and without 'edit' and with and without various field
overrides.
  - General behavior seems correct (messages look accurate, and have the
expected information). Special fields like "Reviewed By" and "git-svn-id" seem
to work correctly.
  - Edit behavior seems correct (edit mode shows all editable fields, hides
fields like "Reviewed By").
  - Field overwrite behavior seems correct (overwritable fields show the correct
values when overwritten, ignore provided values otherwise).

Phabricator is a open source collection of web applications which make it easier
to write, review, and share source code. Phabricator was developed at Facebook.

This is an early release. It's pretty high-quality and usable, but under
active development so things may change quickly.
