Changed lots of stuff!

* Makefile
* snowcloud now creates PNGs! It'll place it in test.png in the current directory
* More of a mess of code! (I'll clean through it soon, I promise!)
* Removed unused odds and ends (hopefully including the entirety of
  the CloudApp API, you can get that on the cloudapp github anyway)
* Removed what should be all mentions of old program name
* systray.c is now gfx.c to maybe somewhat explain what's being done a
  bit more
* Added gitignore to clean things up
