Graal 2.05 bug fix release

[Admins]

I have uploaded a bug fix release. Start the
setup.exe to get it.
Here a list of the bugs that have been removed:

- the script variable playerscount is fixed
(was not working for npc weapons)
- when you create a new level then the current
background tile is used for the background (instead
of a black tile)
- when switching to other servers then the correct
server name is displaying in the window title
- openurl2 works more than one time
- hidden npcs can use the command showimg
- when the map is changed (script command setmap) then
the new map is immediatelly applied
- the little yellow hint window that shows the names
of players on the minimap is hidden when you switch
to other applications
