linuxdvb: I actually have something resembling diseqc config.

I still need to actually be able to properly set it from the UI and this
is one area where the very generic UI really does feel clumsy.
iptv: minor addition to debug output
linuxdvb webui: starting to get a very rough editor for satconf

This is still very crap, but if I can get "something" it'll be better than
nothing at this stage.
