Added support for LG Devices Running KitKat. Fixed two little bugs....

Added support for almost all LG Devices Running KitKat.(I checked the code of G2,G-Flex,G-Pro,G-Pro 2,G-Pad only but It will probably work on all LG devices running KitKat)
Fixed two little bugs: 
1)Touch color in ScreenColorActivity was actually always the color of pixel(1,1); 
2)Unlinking Status And Navigation Bar color setting only for some apps was ignored
