Quicksettings 3.1
Minor post update.

* Update Recents animation with new immersive modes. Continue this AOSPA/android_frameworks_base@48be6b1
* Sleep Tile
  Cleanup code.
  Add new holoish drawable.
  Long press now opens power menu (pure emulation of power button). Thanks to @cristianomatos
* Immersive
  Back on our first concept of having the tile dualized and change it:
  - Front: Toggles Global On/Off.
  - Back: Toggles modes (Full/Nav only/Status only).
  The tile now stores last immersive state, thanks @David96 for the idea.
  Fixed a critical bug with status bar hidden only, thanks to @David96.
* Rssi Tile
  Restore long press action to data usage on front rssi tile
  Fix icon overlay, restore blank overlay on disable and while wifi is on.
* Code indenting and cleanup.
* Update dual switch icons, less bright.
* Restore a previous fix that relays on immersive.
* Get rid of some useless imports and code in quick settings, make a class for battery tile.

PS2: Update dual switch icon brightness.
PS3: Spanish translations.
PS4: Translation fix.
PS5: Translation derp.
PS6: Cleanup.
     Add battery tile class.
