[vdr] PATCH: Source dependant new channel insertation

[Christian Schuld <chris@sonnengesicht.de>]

Hi,

attached you will find a small patch, which lets vdr insert new found channels 
after a source dependant group seperator (:New Channels @<Source>).

This is quite usefull in case you have more than one sources and exterm 
usefull, if you have a moveable dish with the ability to receive many 
sources ;-)

Klaus, may be you can consider to include this small patch in the next 
release?

Viele Grüße
Christian
