Nano Obssession: Chromeless window, Styles

Does the following:
 - Adds 'chromeless' mode (NanoUI defaults to using this)
  - Window borders disappear, replaced by in-browser elements for
    minimize/close/move/resize.
  - You *must* move/resize slowly when using this mode, or it can have
    unexpected results, as the JavaScript cannot keep up as well as the
    native windows movement.
 - StatusGroups are now transparent: This looks nice. That's about it.
 - Body background switched to a .svg format for the NanoUI Logo.

 - Coder things:
  - Nano's JavaScript now has a new class, NanoWindow
   - NanoWindow handles all of the chromeless work. It'll be used to
     replace portions of NanoStateManager later.
