[Deskbar] cuemiac

Here's what I have so far about the CuemiacWidget... Not anywhere near
completion yet. Just though I'd share.

Just run "python cuemiac.py" to see it in action.

If you edit it please keep it clean from deskbar imports so far. It
eases debugging wuite a bit. Ie. just copy-paste the bits in you need.
