* Icons

* Better key mappings, brightness control, better gamma correction, more effficient framebuffer

* Cleanup stage 1

* Cleanup stage 2

* Make the build system build a g3a

* Make it not exit when you press the menu button

* Add Casio port to README

* Use omega-master instead of omega-dev

* Fix mistake with cherry-picking in the README

I'd like to add an option for this though as I prefer the ones from Epsilon
