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.) git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/trunk@212 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
