The header QMetaType must now be included explicitly if no other header includes QObject. Adjust band combo box layout settings to ensure it is rendered at minimum content size otherwise it stretches the signal meter width to an ugly extent. Also retired the "frequencies" settings file key so that upgrades and downgrades between 1.5 and 1.6 no longer require rebuilding the working frequencies list. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@5727 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
