====== About the script ======
  * Purpose : This script will autoindent and remove unneeded spaces and tabs in other scripts
  * Author : [[https://plus.google.com/+LukasMorawietz|LM13]]
  * Current Version : 2.0
  * Link : https://plus.google.com/115366157037831519359/posts/RjizoNAYKsc

====== Changelog ======
  * Version 1.0 (22/7/2014): initial release in wiki
  * Version 1.1 (23/7/2014): line breaks stay as they are, fix for strings and comments, double spaces and backslashes
  * Version 1.2 (25/7/2014): fix for backslashes, keywords, added switch support
  * Version 1.3 (29/8/2014): option to write directly to script files (default: on)
  * Version 2.0 (14/9/2014): new UI, option to format all Scripts



====== How to use the script ======
  * Run from anywhere
  * choose something
  * copy/paste the output if not using directWrite

====== Issues and Hints ======
  * When formatting all scripts it really may take some time! Don't click anywhere and when a Dialog pops up "LLX is not reacting" tap wait.
