Fixed tons of bugs:
 - /trade add (currency) not working properly (6 values where 7 are required in the db)
 - /trade list not showing items at all (pages still don't work)
 - Users not being able to cancel their own trades
 - /trade search now properly shows the required format for the different trade types
