--[[ 
"Clean Tags" -- An Auto4 LUA script for cleaning up ASS subtitle lines of badly-formed override 
blocks and redundant/duplicate tags
* Designed to work for Aegisub 2.0 and above (only pre-release version was available at the time of 
writing) @ http://www.malakith.net/aegiwiki
* Requires cleantags.lua to be available in automation's include folder
* The changes performed on your subtitles are guaranteed to be undo-able provided that Aegisub's undo 
mechanism works. Even so, I am not resposible if it damages your subtitles permanently, so please 
back up your subtitle file before applying the cleaning up
