Introducing LightUI

Based on TRDS from Slim ROMs.

Dafuq is LightUI?

LightUI is just like inverted ui aka TRDS and switches the user interface to holo light (white).
TBH I was bored of inverted this and that so I sat down and got this up and running.

What this commit does:
Adds new qualifier "lightui"
Adds holo blue images to go with white background.
Switches the font to black.
Works with all the apps. Just add folders with lightui (drawable-lightui-xhdpi)

A big thanks to David Zeraie aka vicino

Thanks to Slim ROMs for TRDS and @kufikugel

What do you think @kufikugel ?
