====== About the script ======
  * Purpose : This script will fill any container with all of your apps, like an App Drawer
  * Author : [[https://plus.google.com/+LukasMorawietz|LM13]]
  * Current Version : 2.0
  * Link: https://plus.google.com/115366157037831519359/posts/4F9TpMfz2fv

====== Changelog ======
  * Version 1.0 (18/7/2014): initial release in wiki
  * Version 1.1 (20/7/2014): added optional horizontal sorting
  * Version 2.0 (23/7/2014): Removed autovalues, due to an unfixable bug, added item remove and add again



====== How to use the script ======
  * Set the script in the resumed event of the container
  * configure what you want at the beginning of the script 
  * enable the script for Lightning and item menu
  * if you don't want to see an app in the new app drawer, run this script from the item menu
  * to re-add items, run this script from lightning menu

====== Issues and Hints ======
  * As the script is based on the original app drawer, you may have to load the original app drawer once to detect installed or uninstalled apps
  * first load may take some time
  * don't hide the icons in the original app drawer. 
  * if you delete items in the normal way, it will cause an error

//please report all bugs in the g+ community!//
