Summary:
Share code with the new PhabricatorDifferenceEngine, which handles diffs with no
changes correctly.
(This isn't the same issue as file moves, but I ran into it while generating a
repro case.)
Test Plan: Previously, changes which didn't change file content (e.g., property
changes) would throw. Now they work.

Summary:
This is really rough and needs work (particularly, there's some diff code I
really need to refactor since I sort-of-copy-pasted it) but basically
functional.
Show text changes between diffs and allow users to revert to earlier versions.
Differential's line-oriented diff style isn't ideal for large blocks of text but
I'm betting this is probably good enough in most cases. We can see how bad it is
in practice and then fix it if needbe.
I added a bunch of support for "description" but didn't add the feature in this
diff, I'll either follow up or task it out since it should be a pretty
straightforward change.
Test Plan: Looked at history for several Phriction documents, clicked "previous
change" / "next change", clicked revert buttons.
