Only table of contents are shown for large diffs by default.

Summary:
Differential used to only show diffs for the first 100 files. Now all
the files are shown in the table of contents and there is a link to
the standalone view for every file. The inline diffs can still be
seen, if user clicks "Show All Files Inline".

Inline comments can also be added in the standalone view, but there is
no form to submit them. The revision page must be reloaded to able to
submit the inline comment.

Test Plan:
