(svn r1090) -Fix: Made the _openttd_revision variable global, and with that
hopefully killed the windows-revision problem. If WITH_REV is defined,
for both Windows as *nix system _openttd_revision is filled with normal
info, else _openttd_revision is set to 'norev000'
-Fix: Small possible server-crash
