annotate gpp/bio/forms.py @ 505:a5d11471d031

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Refactor the logic in the rate limiter decorator. Check to see if the request was ajax, as the ajax view always returns 200. Have to decode the JSON response to see if an error occurred or not.
