I've received my Bluetooth headset today (thanks to Alan Peery!), and thanks to the work done by Faheem, it was easy to integrate support for Bluetooth headset disconnects to headphoned and also test it thoroughly. It also seems that for headphones *without* microphone, Hal does not detect a device disconnect, so I had to leave the state file-based code in there. I did some clean-ups, re-added support for Diablo, but removed the volume control code (which didn't really work on Diablo and is unnecessary on Fremantle).

In short: headphoned 1.6 with Bluetooth support is currently going through the autobuilder, and should be landing in Extras-Devel soon. Again, credits for this release go to Alan and Faheem - thanks guys!

(A side effect is that disconnecting a wired headset with microphone now causes two signals - one from the state file and one from Hal - to be emitted, but for Media Player and Panucci, this does not matter, as they don't unpause when the second "pause" signal is sent.)
