major update. added buddy groups. will also contribute an node access control module which uses these groups ... fixed many many bugs/ugliness, and probably introduced a few. if you are happily using buddylist now, you might wait a while until these changes get exercised by some sites ... database update required. i added a column and changed the indices. see the buddylist.mysql file

* use calls to theme_user_list()

* theme('placeholder') usage

- Renamed check_query() to db_escape_string().  Commit announced on the mailing list.

fixed bug in block which caused a warning when a user had no buddies

minor usability improvements

more to come ...
