Rent changes

Gold in moneybags will now automatically be used if you could not
affort your rent. If this happens, all gold from all moneybags will be 
converted into cash, any remaining cash will remain with you of course.

Legends now have a 5 gold free limit per day before they start paying
rent in legend houses (upped from 2.5 gold).

Linkless rent and quit have been modified as follows: They are now
twice as expensive as renting in a city where you are not citizne.
