small typo in greg.py
fixed title parsing

fixed title parsing when ignoreenclosures=yes. Previously the title was parsed
to be everything after the last '=', which was causing youtube rss enclosure titles
to be the same every time, which was in turn causing Greg not to recognize updates
(because the titles were always the same).
