UbuntuStudio controls redesign

[Ricardo Lameiro]

I order to UScontrols to address all of this settings, we should post at the
wiki page the links for the future redesign.
If averyone can post links to tutorials, scripts, HOW TOs or processes to
configure the computer for audio performance. The most info we gather the
better.
I will try to edit Scott wiki page for USControls.
