Make configurations for circular LNBs more convenient

As suggested by Dima73

In Russia, the most popular providers NTV + and Tricolor (satellites 36*e/ 56*e)
. They require a circular LNB. It is difficult to adjust the satellite to
many users. With this patch it will be very convenient as many users do not know the parameters for the circular LNB.

One satellite(36*e or 56*e)-->one LNB(circular LNB)
Reception Settings-->mode Simple-->single lnb-->satellite(36*e or 56*e)-->Use circular LNB -->yes
press ok(save)-->Done
