sidebar style updates for hover states on sub accordion menus
further rejiggering of sidenav and cleanup
cleaning up Fauxton- adding more in the LESS here to be overridden easier w/addons
This line caused me serious head trauma to figure out:

.accordion-list-item:hover ~ div.new-button .dropdown-toggle{
        color: white;
      }

But it works :-)
refactoring hover and positioning
adding icon update placeholder for side nav sub menus (eg. map reduce and meta data). Need to figure out icon compiling.
