Issue 28

Hi,

finished creating announced patch for external volume control. There are two new config parameters that allow to control volume via scripts. Works quite good so far but have problems when switching from and to SenderReceiver mode. I am not sure wheather this comes in with new code or maybe a problem that already was there before. But I will go on testing. Hope you like the code. I’m not a c++ professional.

Applied through patch, with small changes.
