DoomLegacy 1.47 testing

Testing of DoomLegacy 1.47 has started.
Due to adding support for MBF, this will more testing than usual. If anyone wants to help testing with the new DoomLegacy 1.47 then please download it from the SVN repository, current head.
There is also a new network version, and a new savegame version, so those will not be compatible with previous versions.
There may be a few more bug fixes, as I am going through the old bug reports.
Thanks, Wesley Johnson
