Static storage variables that should have been class members are made so. This ensures that if they are used as initialization one time switches then they will operate correctly when their class instantiated more than once. This now happoens for most classes due to the configurations switching facility which destroys all windows and re-instantiates them. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@6661 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
