Initial commit of buddylist.module, which allows users to maintain a personalized list
of friend's on the system.

Also included in the module is a block of the last 10 friend's blog updates, and a block
displaying your buddies.

Also optionally the ability to customize the user list blocks
(buddy list and who's new at this time) to display an icon next to the names for adding
and deleting buddies without having to go to their profile screen first.
