[WIP] Quicksettings 3.0

* Improve code (cleanup, indenting, redistribute resources, some comments updates).
* Fix: Restore stock aosp transition for quick settings on rotate (the rebuild animation
       executed when you are on quick settings panel and rotate the screen is not always showed).
* Animated Dual Tiles
  Animation: Use flip animator classes by xplodwild (OmniRom).
  Use aosp quick settings classes and methods to build dual tiles.
  Make dedicated classes for rssi/network tile.
  Change the original flippable tiles concept making them dual tiles for real.
  Integrate dual tiles into edit mode (TESTING).
  Tiles added:
      -Wifi AP Tile (Dual): Made the aosp way. Created receiver for the main intent sent to change
       wifi ap state (also toggling with apps will refresh it). Integrated with Wifi Tile. Thanks
       CyanogenMod for the drawables.
      -Screen Timeout Tile (Dual): Integrate it in the sleep tile. Cleaner implement. Thanks Yanuar Harry
       for improving the behaviour :)
      -Bluetooth Extra Tile (Dual): Original from OmniRom. Build and update it with android’s
       stock classes and methods (aosp basic tile's). Toggles discoverability.
  Tiles cleaned/updated:
      -Immersive Tile: Cleanup and store its resources to QuickSettingsModel with their own methods.
      -Brightness Tile: Long click toggles auto-mode.
      -RSSI Tile (Dual): Simplify the code. Show off indicator when data is disabled. Merge in Mobile Networks
       Tile.
      -Cleaned Wifi one and general cleanup for the others.
