Unofficial build of CyanogenMod 11.0 for Galaxy Note GT-N7000

This is an unofficial build for all those who want to stay with CM11. The build is based on the pure CM code and does include the stagefright patches and other patches up to July 30.

It does run perfectly on my wife's N7000. However, use at your own risk.
