Now uses wiringpi2 instead of wiringpi.
I made this change because the install instructions in README.md failed (it wouldn't let me build wiringpi-python as I didn't have a necessary C header or something). I thought it'd be nice to get the module working in a more straightforward way, using pip to install wiringpi2 (which seems to have superceded wiringpi) rather than the git submodule method in the readme.
This commit means you can just run sudo pip install wiringpi2. The only relevant API difference seems to be that wiringpi.OUTPUT is now wiringpi2.GPIO.OUTPUT in wiringpi2.
I've successfully run a "real world test" with an RF transmitter on my Pi B+, and I also successfully ran the unit test for the RF sender. I'm not able to test the receiver as I don't have a receiver hardware module.
Hope this helps! If the changes I've made don't make sense then that's cool - let me know if I've unintentionally broken anything. This library rocks!
