ALSA Scarlett Control Panel (alsa-scarlett-gui) v1.0 beta

A Linux control panel for Focusrite Scarlett, Clarett, and Vocaster USB audio interfaces — the equivalent of Focusrite Control / Scarlett MixControl / Vocaster Hub on Linux.

Configure routing, mixing, input/output levels, DSP processing, and firmware updates through a graphical interface.

This is a beta release — better than 0.5 but not quite 1.0. The docs still need some updating.
