comparison gpp/custom_search.py @ 438:524fd1b3919a

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fixing #214; don't need a custom model search view. All the info is in the template. Wrote a template tag to extract the info from the request context and urlencode them.
