Add 'satellite config' column to Configuration -> TV Adapters -> Service table. Fixed preffered spelling typo. 

The 'Satellite config' table is available on the 'Multiplexes' table. It would also be helpful on the 'Services' table. This uses pretty much the same code, ie 'Satellite config' column will only show up for satellite tuners. Also fixed a typo with the spelling of "preferred".
