Fixed zoom detection for webkit(desktop)
fixed Issue #41 (Uncaught Type Error)
Use webkitRequestAnimationFrame to detect webkit since webkitMarquee is gone in the Chrome betas.

document.body.style.webkitMarquee can be expected to be gone soon in release version as well.
Update the webkit detection to work again.
Change webkit zoom detection to work with SVG.
Merge remote-tracking branch 'remotes/bitwire/master'

Conflicts:
	detect-zoom.js
removed the minified file (everyone has their own minification process anyway)
augment the demo file with the info available at http://stackoverflow.com/questions/1713771/how-to-detect-page-zoom-level-in-all-modern-browsers and http://htmldoodads.appspot.com/dimensions.html turning the demo page in a full-fledge diagnostics page.
