WSJT-X/revision_utils.cpp
Bill Somerville 241033d49b Try to form a consistent program title and revision specification from
all types of build.

CMake builds use 'svn info' (the git-svn equivalent is also supported)
to  get the  real latest  revision of  the workspace  that is  used to
source a  build. If the sources  are not in VCS  workspace (build from
source  snapshot  archive for  example)  then  the  $Rev$ svn  keyword
expansion in mainwindow.cpp is used despite its issues with accuracy.

Non-CMake builds use the $Rev$ keyword expansion where possible.

If a CMake  build is from a VCS workspace  with local modifications; a
'-dirty' suffix is added to the revision number to denote that.

If no revision number information can be found the word 'local' is
used as a revision number.

The revision  specification is used in  the WSJT-X "about"  box and is
sent  to PSKReporter.info  as part  of the  local  station information
(this     can     be     viewed     at     the     statistics     page
http://pskreporter.info/cgi-bin/pskstats.pl).
