NEW - Updated/Actively Maintained RF24 Library Fork

[TMRh20]

Hello, since this is the main lib and it doesn't seem to be maintained anymore, I just thought I'd mention here that I've been maintaining an updated/optimized fork of the library which simply builds upon the foundations laid by maniacbug, and incorporates changes (among others) from the stanleyseow , gcopeland , and jscrane forks. Many if not all of the bugs/issues are also fixed, and it supports hardware from ATTiny to RPi and Galileo. It seems I cannot submit a pull request, because someone already submitted one with a slightly misleading title, #45
