Enabled spellcheck in ST2. US English mode though.
Implemented players password authentication. Not tested yet.
Implemented calling player = current player check
Added documentation + removed the password authentication when submitting a transaction: If we already pass the object reference, there is no point passwing the password as well, if one has access to the object one has access to the password anyway.
Passing different copies of the objects to the different player, as the first player could tamper with it!
Debugging everything. Passwords are now correctly checked, transaction correctly validated, cheater players correctly banned. Still need to check that everything really works, though.
