Code review comment for lp:~mwhudson/loggerhead/fix-empty-files-page

This branch fixes the files view in an empty branch.

I think there must have been a mismerge at some point -- there was weird, half-duplicated code in inventory_ui.py. The code isn't maximally clear yet, but it works at least :)

I added a test and converted the existing tests to use bzrlib TestCase's (prompted by bzr-avahi going nuts while running the tests with py.test :).
