Fixing UI data pipe line, re-rendering:
- store section DOM Elements in gr-diff-builder
- find diff section by line range
- store collapsed lines as gr-diff-group
- update gr-diff-builder's data model on expanding collapsed lines
- .right/.left CSS classes applied to td.lineNum instead of .content

If gr-diff recognizes that the file difference it's representing is
between images, it uses a different diff-builder that displays images
in a side-by-side-manner. In this case gr-diff will also make requests
for the image data itself, which it can pass down into the image-based
diff-builder.
Adds methods to gr-rest-api-interface to support rendering the data
relevant to image diffs. For images that are revisions of the current
change, provides "getChangeFileContents". For images that come from the
parent tree (i.e. if the basePatchNum is "PARENT") the interface
provides "getCommitInfo" to determine the SHA of the parent commit, and
"getCommitFileContents" which can get file contents for a given commit.

Adds gr-diff-cursor, which is a specialized cursor for navigating
through diff content. It tracks the diff line being targeted, and, in
side-by-side mode, it tracks the side of the diff being targeted.
Also includes special behavior that ships blank spaces and other
non-commentable content in diffs, as well as automatically switching
sides when appropriate.
Support for more than one diff.
Also updates the diff builders to emit some useful element classes.
Note that this only adds the diff cursor along with tests. This is
setting up the work to actually add the diff cursor to the diff views.
