4d5331899b When using click-to-decode in FT8 (nagain=.true.), the regular noise baseline estimator fails, producing erroneous and very large SNR estimates. Revert to the older signal-to-noise-plus-interference calculation for click-to-decode.

73df0d00ef 1. Alt+F8 arms "Call 1st" as if a CQ had been sent.
2. "Call 1st" label turns red when armed to respond to a caller.
3. Suppress some recognizable false decodes, send them to cumulative file
   "data_dir/false_decodes.txt".
4. Reduce sleep delay in decoder() to 10 ms.
