CyanogenMod 6 V6.1.0-RC4 for z71

"This is an AOSP-based build with extra contributions from many people which you can use without any type of Google applications. I found a link from some other project that can be used to restore the Google parts, which can be found below or elsewhere in the thread. I've still included the various hardware-specific code, which seems to be slowly being open-sourced anyway.

Visit the CHANGELOG for a full list of changes and features!

All source code is available at the CyanogenMod Github!
