/*
 I refactored wikiswap, finally, and mainly so I can leave maintenence to people
 who are actually active. It's now extensible, and you can do whatever
 you feel like with it. For basic usage, pass it a hostname of another wiki, 
 a title, name, and unique id. However, you can now do a couple of fancy things
 using the modifier parameter.

 For instance, say I wanted to add a tab to search google images for the page name, 
 but only within a certain site.

 For this, you'd call:

  wiki_swapper('http:images.google.com/images?q=', 'google', 'Google Image Search', '_gis', add_site_search);

 Where the function add_site_search is defined as follows:

 function add_site_search(href) {
    return href + "+site:wiki.guildwars.com";
 }

 or, if you wanted to restrict the tab to certain namespaces, you could call a modifier like this:

 function modifier_func(href) {
   if(wgCanonicalNamespace == 'foo') {
       return false;
   }
   else {
       return href;
   }

 If the modifier function returns false, the tab won't be added. So, the modifier needs to take a 
 href as a parameter, and then either return the path to be used, or return false if no tab is to
 be added. Of course, you'll also need to include this page, or just copy the wiki_swapper and 
 addTab functions to your own monobook.js.

 Have fun!
