	An ambiguity existed between release candidates and development versions as there was no definitive identification for development versions. Added a new version number suffix of '-devel' which appears if the release candidate number is missing or zero in Versions.cmake and the revision is not marked as a release version, also in Versions.cmake. Also re-factored setting of version number suffiexes to a single place in in CMake/VersionCompute.cmake. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@4422 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
