annotate gpp/weblinks/views.py @ 11:cc8eb028def1

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Update jquery-ui and theme version that is hosted on google. In preparation for having jquery on every page (?), make it so that the autocomplete plug is using the 'global' jquery, and not the one that came with it. It seems to work okay with jquery 1.3.2.
