Changes the wiki proc to accept player input to reach a specific page, or search for one if the wiki can't find it.
You can use it by typing 'wiki [query]' in the command box, for example 'wiki cult' brings up the cult guide, or clicking the wiki button at the top-right and typing what you want to look for.
It uses wikiurl, so other servers should be compilable, if they change their wikiurl.
