Space > Indent in roomauth; add targetUser for hex

/roomauth previously had spaces instead of tabs except in 3 lines (however alignment of code was correct) and /hex would be better with targetUser. Inspite of all that, I don't really know how !targetUser (and targetUser) will react to how I placed them, so it'd be nice if you would confirm that and PM me on Frost regarding the matter. If there are no problems, you can merge this (obviously).
Quite a few fixes.

Added a few spaces to make code neat, fixed some indentation problem in /friends, add a pmfriends command in commented version (not sure it'll work and can't test it right now) and a grammar error where I had "Click" typed twice.
/usersofrank update.
