Changed the string formatter from % to f"",

Fixed a bug related to logging [log dir does not exist on master, and needs to get created on first startup]
Added !prefadmin <user> to view preferences of players, and change them
Orgrank & name will be hidden in !alts, if the character is not in an org
Page prefix & suffix are now being relayed [for example, it affects !online
Fixed !perks
