cleaned up the indexer code: - it splits more words out (much simpler, faster splitter) - removed code we'll never use (roundup.roundup_indexer has the full implementation, and replaces roundup.indexer) - only index text/plain and rfc822/message (ideas for other text formats to index are welcome) - added simple unit test for indexer. Needs more tests for regression.
