MediaWiki/Special/Interwiki

Overview
This is a modified version of Extension:SpecialInterwiki by Stephanie Amanda Stevens. It adds the following features:
 * Interwiki URLs are shown as links, so you can quickly check validity (and answer the inevitable "what the heck is that wiki?" question more easily)
 * Compatible with MediaWiki 1.14 (there was a class name conflict)
 * Version data has link to this page (original extension had no URL)
 * Description changed to shorter "Interwiki alias management", so it will be where you expect it in the list (under "I" instead of under "V")
