annotate gpp/downloads/views.py @ 429:d0f0800eef0c

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Making the jquery tabbed version of the messages app the current version and removing the old. Also figured out how to dynamically update the base template's count of unread messages when messages are read.
