handle gaps in channel numbers, and in preparation for unique channel ids).
- Fixed slow reaction on SVDRP input (thanks to Guido Fiala for reporting this one).
- Added KI.KA to channels.conf.cable (thanks to Robert Schiele).
- Frequency values for cable and terrestrial channels in 'channels.conf' can
now be given either in MHz, kHz or Hz. The actual value given will be multiplied
by 1000 until it is larger than 1000000.
