Pass the temporary directory to jt9 and use it to give the correct paths to temporary files. Also jt9 passes the absolute path to kvasd.dat in the temporary directory to kvasd. Clear out all the annoying cruft that has accumulated due to having to run with $CWD as the temporary directory. Use QStandardPaths to find the writable data directory where needed rather than passing it around between objects. This now works because the $CWD hasn't been changed. Do away with the CMake option WSJT_STANDARD_FILE_LOCATIONS as it is no longer needed. Fix astro status file azel.dat formatting. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@4732 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
