Fixed long problem with tuning to frequencies like; 12669500 Hz which is not possible with the old satellite plugin, because it reads 12669,5 in kHz and could not be expressed.
* Frequency, symbol rate, LNB_LOF1, LNB_LOF2 and LNB_SLOF are in Hz now. Input methods "dvb", "qpsk", "cable", "terrestrial" use this policy.
* Added backwards compatibility with access method "satellite" as used by the GUI; frequency and symbol rate are interpreted as kHz.
