Added javascript QR-Code library
Changed QR-Code CSS (selector and attributes)
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.
Removed jQuery from almost all pages

jQuery has been removed from all pages, except those who really require
it (like autocomplete in link edition).
Immediate gain: All pages weight 286 kb LESS !   \o/
Highlighting in search results has also been temporarly removed (and
will be re-implemented).

Focus was not properly given to description field when it's empty.

A real "Stay signed in": keep the connection

Instead of trusting the php session, it uses a cookie. The php session
sooner or later is distroyed if not used. It depends upon the server
settings. Using a cookie ensures that one really stays signed in.

Dev notes: I wanted to avoid merge conflicts, stay with the main
developper standards and keep the "index.php" in one file. That's why
the code may not be that nice. My own dev level my also explain.
