added Textures for screen overlay and textboxes
can remove lines that are filled

can rotate and move active piece
can draw active piece
to do: collision and adding piece to the back
added moving the active piece and rotating it

adding the piece to the background and collision detection is broken :(
and its all my fault, I think it might have something to do with the way I'm comparing the active piece's position in the grid and the blocks in the grid.
fixed collision and adding piece to the background
semi working game

added gestures for moving and rotating
resets game on lose spawns blocks above the playable area
