New QR-Code generation code
* QR-Code generation now uses a client-side javascript library instead of an external service. This is better for user privacy. * Library used is http://neocotic.com/qr.js/ (11 kb). * jQuery is no longer used to display QR-Code (this is a first step in removing jQuery entirely). * This library is loaded *only* if the QR-Code icon is clicked. * If javascript is disabled, it will fallback to the external service. * External service was changed from "invx.com" to "qrfree.kaywa.com" because invx has become bloated. By loading the javascript library *only* if the icon is clicked, it will prevent the 11 kb lib to be loaded in every page.
