Adaptando movimento ao D-Pad
Added map limits, somewhat map adaptativity (one screen only though).
TODO:
	- fix choppy animation when moving (fps);
	- see ToDo list at the group for more details.
Merge branch 'DPadCreation'

Bug:
	- DPad allowing clicks outside.
	- even in landscape mode, some methods returned portrait metrics.
