SageTV VDR Integration

Extensions to use VDR as a recording/EPG backend for SageTV.

There are 2 parts:

* An extension to the excellent  streamdev plugin to act as a SageTV network encoder.

* A Java class to import the VDR EPG into SageTV

The code is at a very early stage, expect it to gracefully crash when you invite your friends for a movie evening.

Channel numbers in VDR must be continuous. DVB radio does not work yet, but this should be possible using the external remux capability of streamdev.

All the code is  GPL
