 attached patch fixes strange behavior reported in #4052 where some away
 messages are in html and others are not, and randomly switch back and
 forth.

 basically the call to aim_locate_autofetch_away_message is unnecessary,
 because buddychange snacs already contain each user's away message and
 aim_info_extract is able to pull it out. the extra calls to
 locate/user_info can cause rate limiting if you have a lot of buddies that
 are away.

 this also means that the locate/user_info snac is only necessary for
 serv_get_info, and the data passed to purple_got_infoblock should not
 update the buddylist, because it contains an html version of the away
 message. this html version should only be used in the user info window's
 html view.
