Make queries for communications easier, all you need is a users.id queried, the system will find everything else for you
Add ability to use [PASSWORD], [USERNAME], [EMAIL] (tries accounts.email first, if its not there, it uses accounts.pendingemail), in _ANY_ email. [REGNUM] also added but will obviously only work for participants
Add "all" section to the tabs list for user editor, so a user without any roles can still get the basic pages like "account", "roles", and "personal info"
Put count on participant invitations for teachers (and superusers)
Fix a bug where changing a password for a different user didnt work (it changed YOURS!)
user_invite can find users by username OR by email address
if the account is found, but user_load fails, thats okay, it just means that they dont have any roles yet
