1. New routine "ftpeak65" for peaking up in frequency and time, and for AFC.

Browse Source 
2. Removed the "itry" loop in wsjt65, speeding up JT65 decodes.
3. A dded Deep Search to avemsg65.
4. Changed "Decoding" menu accordingly.  Karn RS decoder used only if KV
   decoder not present.
5. Removed sort from deep65; find 1st and 2nd largest values directly.
6. Fixed Makefile.win.  (Still need to fix *nix Makefile.)
