WSJT Old SVN

Added a manpages sub-project to generate man pages for wsjtx from
AsciiDoc source.

Add items required by Debian packaging and Free Desktop Standards.

Add better command line processing to wsjtx including version and help
options.

Add a new command line option 'test-mode' that invokes the Qt test
mode where all writable file locations are moved to a common
directory. This is to allow application testing from a repeatable
start point rather than have the test application sharing files with
normal operations. See QStandardPaths::setTestModeEnabled() for
details of the test location.
