Graal v4.01 revision 13 released

[Admins]

Download the new version by connecting to the server list (login server).
Updates:
- fixed the problem with filenamecache.txt and not seeing the start screen graphics
- when being disconnected from a server then going into the offline test mode is not bugged
- the script error 'Function bind not found' on startup is not displayed anymore
- the profile variables field is read-only

Also a few problems in the new scripting engine for the npcserver have been fixed, enableweapons() and disableweapons() work correctly now.
