Take advantage of the new KVASD v1.12

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.
