Added my nasty 'solver' with autoplay and pause mode.

Basically what it does is send right and down arrow keys until this doesn't change the board anymore.

Then it sends down and left, and resumes the previous method.
Depending on pure luck (wether a new '2' block will emerge in an unhandy place) 
it will either solve the thing until oblivion or require you to sometimes pause it and merge some by hand.
