Add channel number to parms passed PostProcessing.bat

[wtg]

I know this has been mentioned before, but I didn't see it in the wishlist. If channel number was passed to PostProcessing.bat, we'd be able to:

• skip comskip processing on files we know have no commercials
  
• have comskip process files differently based on the channel number

Sub says here that this will be available by the end of the weekend in the next version. woohoo!
