Dual Player Support + Controller Support

[venegu]

The ability to have two players play at once would be a wonderful feature to implement (think co-op games such as The Lego Movie Game). This could be done in one screen by having one main player and whenever the other player gets too far from the main player (or is out of the screen) they will be teleported next to the main player.

A big concern is that sharing a keyboard might be annoying to the users, so the best way to approach dual player support would be to have controller support (Xbox and PS3 controller).
