Replace Lucene search for Review Requests with Haystack and Whoosh.
Full-text search with Lucene is a hassle to set up. Haystack and Whoosh are

pure python so it's easy to include them with Review Board and have full-text

search available out of the box. Regular maintenance of the search index is

still required for the search function to return up-to-date results.
These Review Request fields are indexed : id, summary, description, commit_id,

testing done, bugs, author (submitter's full name), submitter (username),

filenames of the files in the diffs (diff content is not indexed).

Enabled and disabled search in General Settings and changing index file path and results per page,

followed by rebuilding the index.
Search using the following fields:

id, summary, description, testing done, bugs, author, submitter, diff filenames.
Built and inspected Sphinx docs.
Built and updated the index through rb-site.
Unit tests passed.
