Created a game mode manager

There is now one location for information relating to each GameMode instead of several places, so that info can be easily updated and propagated to, for instance, GameModeSelectionLayer. GameModes can also be specified by an info instance each owns. There's also a way to get an ordered list of game modes.

The three star game mode unlocking system has also been added.

Closes #213
