Settings: Add CM PlatLogo & CMCaseView (1/2)

* 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 PlatLogo if the width of the
  PlatLogo is bigger tham the actual device width
* Added CM mascot drawables

ToDo:
* Make DessertCaseDreamSettings work
