* Wrap $refreshedTOC in an isset() to prevent warnings on (some?) special pages
* Removed $myTitle variable and used the proper variable instead so that things like special pages' titles are shown correctly (i.e. the title on Special:UserLogin/signup is shown as "Log in / create account", not as "UserLogin/signup")
* Tweaked "sidebar" rendering code to allow for things like ShoutWiki's NewsBox extension to render properly instead of only the title being rendered
