Added the Vaisala RS41 data packet decoding.
Changed the default freq from 402.0 to 402.7 Mhz, since it is more popular freq.
Lowered the frequency stepping, so it is easier to fine-tune the exact freq center, if needed.
Sonde's Serial ID is passed into the VIEW MAP, so now the sonde is labelled on the map.
Made MenuView use less widgets, hopefully preventing crashes with large
lists
