  I've forgot about WINEPREFIX here but when I added it there is a 
problem that wineprefixcreate is called with a directory like 
~/.wine-F6YHsT . If we make a reference to such a directory it won't work.
  Maybe we could keep it that wineprefixcreate creates the default file 
and document somewhere how to create the menu files if someone creates a 
custom wineprefix. Alternatively I could add a parameter to 
wineprefixcreate with the final name of the directory and make the menu 
filename dependent on this path.
