Added .gitignore for all crud and removed crud

@isupeene Hello!

Added a .gitignore to remove all eclipse, java, android, and OS crud.

THIS WILL BREAK YOUR ECLIPSE PROJECT (if you haven't already)

but if someone else has some other Ecplise settings ('cause, you know,
customization), you won't be overwritting their settings with every push.

Cheers!
