	 v 1.0 beta 2010-08-30 changes from Ronald Heft's Analyticator 6.1.1 version
	
	1) Use onmouse up instead of onclick in order to track all mouse clicks (left, center & right buttons).  Side effect: keyboard enter won't be tracked.
	2) Allow separate configuration of page view vs. event tracking for outgoing links and downloads.  For downloads, allow for configuration based on file type.
	3) Allow for parameterization of Event category lables.

	Open issues: 

	a) should external downloads be tracked as downloads or external link clicks.  Currently tracked as downloads.
	b) would like to track onclick + oncontextmenu events in order to track left, right mouse buttons + enter key.  Currently tracking 3 mouse buttons.
