CidKat: Changes to toggle between CM and KitKat

* Based on Danesh M commit from 10.1
* Always use "K" letter for android version easter egg since
  some devices override BUILD_ID and the letter "J" appears instead of "K"
* Add some padding (left & right) to the Android/CM logo
* Added CM mascot drawables

Todo:
* Make the dream settings work
