/* WarpzGA 1.0 (June 2010)
 *
 * Warpz Event Tracking for Google Analytics (async)
 *
 * By Fini Alring <bytefarmers.com/log/>
 *
 * Initially based on code from Google Analyticator by Ronald Heft (ronaldheft.com)
 *
 * Modified heavily for added functionality
 *
 * - Tracks outbound, mailto and download links.
 * - Can use pageview and/or events.
 * - Disregards subdomains (www.domain.com and domain.com will not count as outbound).
 * - Includes subject in mailto if available.
 * - Tested with jquery 1.2 - 1.3 and 1.4
