MPD and Volume widget for Awesome

Here are two small and simple widgets for Awesome WM.

MPD State: Shows now playing artist and song. Works with "Pause" and "Stopped" states. Depends on mpc.

Volume State: Shows current volume status. Works with "Mute" status. Depends on amixer.

Sources and setup instructions are on: github.com.

May be, someone need them. Commentaries and proposals are welcome.
