Fixed a bug in the BBCode parser where every post had ten spaces appended to them.
Added the get_reply() internal API function for plugins to make use of.
Added the bell to the theme.
Fixed some bits of the Cosmo theme where the rowhead wasn't appearing.
Added a "Don't have an account?" link to the login page.
