Add the option to ALT+click a decoded CQ or QRZ message which only moves the Rx frequency to theirs, this facilitates calling a station who is busy and may have many callers on their frequency. Updated the corresponding mouse shortcuts help text. Allow for times with seconds when parsing fast mode and FT8 decodes. Exclude the RR73 grid square from and grid validation or matching, it is not a grid square any more as far as WSJT-X is concerned, it is an RRR substitute. Add a simple state machine for QSO progress such that replies and auto-sequencing can be better controlled. Get compound callsign edge cases working again and allow QSOs from and to compound callsign holders working in as many situations as possible including auto-sequencing and FT8 auto-reply mode. This does mean that a "DE W6/K1ABC DM93" type message close to a callers Tx or Rx frequency will be taken as a reply to a CQ call despite it not being explicitly addressed back to the CQ caller. Compound callsigns should work in MSK144 contest mode also as well as in short code modes with some minor restrictions (short codes will not be used where configuration demands that a message be used to send a full compound callsign). Auto sequencing has been made generic such that it can be used for more than one mode if desired. Allow the use of free text messages to sign off in auto sequenced QSOs without the message being overwritten by the sequencer. Double click actions have been added to the Tx5 radio and push buttons to revert back to the default standard 73 message. Make DisplayText class interface more idiomatic C++ and simplify a bit. Fixed some displayed widget arrangements for different modes and sub-modes so that they are consistent when starting up and when switching mode or sub-mode. This is a big change which has been extensively tested but no doubt there will also be some new defects introduced. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@7939 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
