Comment(by darkrain42):

 After thinking about it more and reading `blist.c` a few more times,
 aluink, the `purple_contact_get_*` should match the `purple_group_get_*`
 function names (get_contact_size, get_contact_online_count).

 Personally, I would also drop `purple_blist_node_set_type` and have
 `purple_blist_node_new` set the type to OTHER_NODE. Someone else speak up
 if that's not a good idea.
