*)  Switch kicad.exe to using KIFACE modules for all major top level windows.
    Eeschema, Pcbnew, and Cvpcb all run under the same process now,
    FOR THE VERY FIRST TIME!

*)  Added KIWAY::PlayerCreate(), PlayerClose(), and PlayersClose().

*)  Factored FRAME_T into <frame_type.h> from ID_DRAWFRAME_TYPE.

*)  Found that the following command line is helpful for collecting all the *.kiface
    files into the <build>/kicad/ directory so that kicad can find them.

      $ cp `find . -name '*.kiface'` kicad/

    Maybe somebody will want to rework how the CMake files are organized so all
    the binaries can go into the same place.  See python-a-mingw-us.

*)  This might fix the problem on the Mac where child process windows were not
    coming to the front.  See ->Raise() in kicad/mainframe.cpp.

*)  You can set USE_KIFACE to 0 in kicad/mainframe.cpp to chain load child exes
    instead of using the KIFACE modules directly, i.e. revert.
