v0.1.0: First version release!

The firmware currently contains all the basic systems for simulating
tetris. However there is some bugs in interruptions and fall_one_row
procedure.

This version contains as well a hardware schematics, the input control
for left/right and a naive version trying to rotate a tetris block.
(using transposition instead rotating properly)

The full row detection is working fine and cleaning as well.
The RNG method for next block selection is totally lame and
this should be change in future releases.

I hope you enjoy it.
