(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
