Bugfixes
Removes old commented code
Adds list_groups()

this should be handled differently
Frontend should get the allowed actions and automaticly display them and give them a key
So definition of allowed acions is only needed once
atm actions have to be defined in Frontend and Turn (and partielly Game)
