 * Script: RecentChangesMultiple
 * Author: Fewfre
 *
 * Uses ajax loading of atom feeds to show the RecentChanges of multiple wikis all on one page.
 *
 * TERTIARY / OTHER / MAYBE?
 *Use "WikiaRss.js" instead of YQL?
 *Display wikis as they are loaded? (semi pain to do, but cool?)
 * * if not: Add option to show all currently loaded wikis when not all wikis can be loaded.
 *Add support for "rollback" if possible to create the uniq id for it
