BrowserStrategy.parseHtmlFromString(htmlString)

thin wrapper around DOMParser.parseFromString or an alternate implementation for Safari
use parseHtmlAsDocument instead of jQuery when loading template source

avoids assets (e.g. paypal web bug pixel.gif) being loaded when RES loads template source
however, hogan's template.render() still loads the assets
apparently DOMParser works fine with text/html in Safari 7

thanks for nothing, compatibility table on mozilla docs
left the polyfill in for safari 6's sake.. assuming it wasn't already fixed for safari 6
