Steven Franke 70b84478f0 Add WW_DIGI to the special activities section. Make necessary changes to
the decoders. Also, an experimental change to the FT4 decoder to base
AP decoding passes on 4-symbol block detection instead of single symbol
detection. This provides about 1 dB improvement on the AWGN channel.
Sensitivity changes on other channels are TBD.
