Updated build with a few fixes:
- The keyboard keys backlight should now be working. There is no support for it in AOSP, so I've tied it to the hard button backlights on the front of the device. When those are on, the keyboard keys backlight will be on. Eventually, I'll look for something I can query in the OS to see if the keyboard is out or not before triggering the backlight. But for now, this is a solid fix.
- MMS is now working in the native Messaging app. No more having to use GoSMS.

Enjoy, and I know this ROM has a lot further to go. I'm working on it as best I can.
For performance increase change "Background process limit" under Developer options (nearly at the bottom of the list) to "2" and see if that doesn't help some.
