Make admin back-end responsive

+ Made admin back-end responsive for all screen sizes
+ Created jQuery script to expand/contract css3 menu.  The menu updates on refresh, using Modernizr
+ Added Modernizr custom build.  Added detection for no localstorage support like in ie7.
+ Added CSS3 icons and fallback script for ie7 and below
+ Fixed part of the download script in ``lib``
+ Drastically improved HTML5 markup, using ``section``, ``article``, ``fieldset``, and ``legend``.  These changes are reflected in the ``form.js`` helper
+ Added Aloha WYSYWIG, but this fails still.  Codemirror is next.
