/**
 * Tutorial script: QuickRC ("Quick Recent Changes")
 *
 * A tutorial user script which adds a "Quick changelog" link to the page skin's
 * toolbox, and when clicked it pops up a dialog with up to 25 recent edits.
 *
 * Demonstrates:
 * - Use of the API
 * - Use of jQuery
 * - Use of ResourceLoader and some of the default modules that come with it
 * - Use of localization
 *
 * (Be bold and improve it!)
