Tvheadend

I pushed my code to https://github.com/seife/tvheadend

For the implementation, I added a third DiSEqC mode "unicable".
If this is selected, the parameters SCR# (channel, variable uni_scr), Unicable Frequency (the channel's frequency, uni_qrg) and PIN (for protected setups, uni_pin) are given to en50494_setup() which is called instead of diseqc_setup(). The value returned from this function is the Frequency the frontend needs to be set to.

It is debatable if EN50494 counts as a different DiSEqC mode, but it fits quite nicely into the implementation IMVHO.

The web UI bits can probably be done better, but I have almost zero knowledge about web stuff, so somebody else needs to do that :)

I've reworked the setup, now SCR#, Frequency and PIN are configured in the Adapter settings, only the port (which is not often needed anyway) is configured in the satconf screen.

The only thing that's left now is (IMHO) to dynamically show / hide the SCR# / Freq / PIN settings only if unicable is selected, but I don't have the knowledge to do that.

rebased the code against current git master, sent pull request: https://github.com/tvheadend/tvheadend/pull/298
