annotate gpp/forums/views.py @ 97:96eec1ed0fd3

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Render the forum page navigation in the view with render_to_string() to avoid doing it twice in the template code. Also undo a mistake in the last commit. Need 2 different orderings for Post objects: by creation date in normal views, and by reverse creation date in the admin.
