Lack of interest XenForo.js - remove TinyMCE old loader

[cclaerhout]

Ref:

    scriptLoader:
     {
       loadScript: function(url, success, failure)
       {
         if (XenForo._loadedScripts[url] === undefined)
         {
           if (/tiny_mce[a-zA-Z0-9_-]*\.js/.test(url))
           {
             var preInit = {suffix: '', base: '', query: ''},
               baseHref = XenForo.baseUrl();

             if (/_(src|dev)\.js/g.test(url))
             {
               preInit.suffix = '_src';
             }

             if ((p = url.indexOf('?')) != -1)
             {
               preInit.query = url.substring(p + 1);
             }

             preInit.base = url.substring(0, url.lastIndexOf('/'));

             if (baseHref && preInit.base.indexOf('://') == -1 && preInit.base.indexOf('/') !== 0)
               preInit.base = baseHref + preInit.base;
           }

It shouldn't be needed anymore, and I'm not sure how it was used without tinyMCEPreInit. May be a very old code then.
