Delegation! Since it's clear that extracting services into delegation

classes is only going to become more common, I've gone and created a
comprehensive facility for creating and using delegates in the place
controller and manager as well as the game controller and manager. With
the pattern nicely set, it is also easy to extend to controller/managers
further up the hierarchy that might need to delegate special methods of
their own. Whee!
