Generic message packing and unpacking routines now understand antipode grid contest messages. These messages are now recognized as standard messages in message response processing and dealt with appropriately when contest mode is selected and applicable (currently FT8 and MSK144 only). git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@8062 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
