zapit: add first experimental EN50494 (aka unicable) support

Browse Source 
This adds first experimental and rudimentary support for unicable.
This will not work with complex setups (DiSEqC-Switches combined with
SCR Matrices etc). Only simple setups are supported.
Also, there is no GUI configuration yet. To enale, kill running
neutrino, then add "uni_scr={0...7}" (only one value, from 0 to 7) to
/var/tuxbox/config/zapit/zapit.conf. Note that the "receiver number" you
probably got for your installation is probably from 1 to 8, so you need
to decrease it by one to get the SCR value.
If your setup has nonstandard frequencies, you might want to add your
assigned frequency as "uni_qrg=1234" (in MHz).

Check the log for those lines if it does not work:
[fe0] tune to frequency 11303000 pol Horizontal/Left srate 22000000
[fe0] tuner to frequency 1553000 (offset 9750000)
VOLT18=1 TONE_ON=0, freq=1553000 bpf=1284 ret=1283000
[fe0] Diseqc cmd: 0xE0 0x10 0x5A 0x9 0x67
[fe0] DEMOD: FEC 2/3 system DVB-S2 modulation 8PSK pilot on, freq 1283000
