Cleans the URL for a title's page on IMDB
When browsing websites the URL often contains query strings at the end like "?ref_=nv_sr_1" to track where you clicked on the link. This helps making visible what areas of a website are used the most. It can lead to a lot of duplicated bookmarks though due to the different URLs. In order to prevent that this script removes the query string after a page was loaded without reloading it.
