[Grml] USERGROUPS=no ?

[Wolfgang Scheicher]

Since still nobody could give me a reason why every user should have his own 
group (or can you?) i prefer setting USERGROUPS=no in /etc/adduser.conf

experimenting with remastering grml i found out that there are some places 
with a "chmod grml.grml <dir>"

( /etc/grml/autoconfig.functions, /etc/init.d/grml-home )

I think by changing this to "chmod grml: <dir>" we would support both ways.
Well, and since i would like it that way, i'm requesting that little change :)
