The Review Board packages (primarily the source distribution) contained

files we didn't want to include, and lacked files we did want to

include. For instance, pyc files were there, but map files were not.

Unwanted doc media files were there, but actual doc source files were

not.
This change reworks our MANIFEST.in to start off by fully including

the directories we want and removing the directories or individual files

we don't want. This gives us a cleaner, but more complete package.

Built the packages and compared their contents to that of existing

shipped packages and the source tree. Made sure they weren't including

anything we didn't want and included everything we did want.
Tested building docs within a source distribution.
