Partial commit.. Im changing my working machine...
Camera prototype completed!
Game now has a camera that starts drawing on (0,0) of the map. It also scales to bigger devices.
I tried to remove the action bar programatically too! But I couldn`t test it.
Game now has a main menu with simple start/exit button. We`ll use that to implement debugging settings!

TODO:
	- improve camera, so it can scroll.
	- start creating newer logic elements for the game, like enemies, attacking and so on.
Fixed the still camera, dpad scale and map limits (the latter partially).

TODO:
	- finish map limits.
	- see previous commit.
Movimentos aprimorados
