Infrastructure and ApplicationController skeleton

Implemented an intial infrastructure to resolve #3.

BONUS: Implemented an ApplicationController skeleton. Check it out @kmdurand, let me know if you have any questions. I'd appreciate it if you could check out this branch and confirm that you can get it to run correctly (print hello world to the screen and the javascript console) on Windows.

Please don't review anything in the `app/build` folder: that's all compiled stuff, but I left it in there in case anyone needs to just drop it in at some point without compiling.

Also added initial documentation and a README to tell people how to get stated on the project.
