Default [KK 4.4.2][ROM]Mackay OMNI ROM (27-Feb-2014)

I have been sharing my CM7/CM9/CM10/CM10.1/CM10.2/CM11-based builds for several devices. MackayROM was first based on CyanogenMod sources, but I decided to move over to Omni as base for my ROM.

About Omni: Omni is a free, community built, aftermarket firmware distribution of Android 4.4 (KitKat), which is designed to increase performance and reliability over stock Android for your device.
Disclaimer: I am not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed. Please do some research if you have any concerns about features included in this ROM before flashing it! YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.

If you run into errors, I may not be able to solve it!

If you know a solution to a problem, either upload it yourself to Gerrit Code Review or contact me through pm.

The ROM is based on Omni sources with the following changes:
-Mackay Kernel:
-Set of cherries picked from gerrit (differing by the day)
-Some additional patches I did myself to the source code

Feature request are OK, but remember:
1. I try to stay close to stock
2. I will not include additional apps, unless they can be build from source
3. The time I spend on features depends on how much I like them myself

Although it is possible to enable ART, this is not advisable:
-Takes long to convert from Dalvik to ART on first boot
-Needs more RAM
-Can cause soft reboots
But off course, YMMV -> light users may have better luck

Changelog of 27-Feb-2014
