Added a decoder for android screencaps.
Converted screencap code to work using mmap()
Generalized the RGBA_8888 type to a unexported screencap type, which should be easier to adapt to RGB888 and RGB565 in the future.
Tweaked the screencap api and tested that it works by encoding the resulting images to pngs
Added code to read a screenshot of a game of dots into a solver.Board.
Added touch event functionality. Taps, and presumably gestures are working on my Nexus with hard coded values.
Read the output of getevent -p to determine touch screen capabilities.
Merge branch 'touch'
