- Added new code for serialization/deserializaiton of full games including initial game and all the player actions.

- Added an undo menu using this code (beware, it's still very very alpha).
- Removed various warning
- Cleaned up avatar loading
- Added full random lists load/save including the deck shuffling (not sure if I could not replace that with seed load/save)
- Moved momir and Co rules configuration out of GameStateDuel
- Create a GameType type to avoid mixing int everywhere
