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.
