Allow the use of js functions inside the wiki

Allow the use of js functions inside the wiki

I understand the security behind removing this ability, but I'd like to use this on a site where I trust the users.

The reason is that I want to make a future content change as easy as changing a single line of code, instead of several, in a situation where content is already prepared in this way.

With the way it's setup, I can't do this with either php, or js in the wiki, because related functions get filtered out.

The only thing I'd like to unlock for this is js functions. Is this possible with an override?
