Heh, i fixed your indentation!
I normally do not care about the coding style that people use, it just need to be consistent. e.g. I use 4 indent spaces in my JS. Also, fixed the @include so it will not need the slash at the end (you never know how stupid the regex engine could be).
I have added the code to the index. Yet your huge post does not give enough focus on the main point of what the code can do:
* It isn't just an improved tag flagging, although it can hide flags well
* It can match inside titles
* And it can exclude by uploader name.
(You said all that but it got quite lost inside the post (IMG:[
