Full featured time management patch for Project Pier. I've developed this outside the SVN so it disregards updates to the application core that exist beyond version 0.8.0.
Patch extends previous time reporting functionality and adds administration views (unbilled, billed, by user, and by project) and the ability for admins to mark time as billed and unbilled.
I'd appreciate if anyone could review the code, I've tested it and it works fine locally. (N.B. Please remove .patch extension).
