Last working version of lunarLander. changes made:
- Made FSM for the random generation of the world. (regPixelAnterior saves the pixel of the previous column, so we can calculate the next randomly going up or down).
- Fixed bugs when cleaning screen (added a multiplexer in ADDRA of the ram, which conects contBarrido to travel all the ram)
- added a BOOM! banner when the ship crashes.
- added check "haAterrizado" to know if the ship has landed at a base.
- added a switch to change between 2 gameplays:
	- sile style: the ship goes down the sile, and then it refuels at the bottom of it.
	- base style: the ship lands on a base, and refuels there. If it goes down at too much velocity (red velocity at the indicator) it crashes. beware, the ship can slip at the base, be careful when landing and dont go out of the base.
- refactored and cleaned bugs
