The stats feature (see https://github.com/grml/grml-
autoconfig/blob/master/autoconfig.functions#L1424 for the implementation) provided us 
some useful data about what people actually use.

Now it might be worth consideration to make this feature opt-in instead of the current 
opt-out (using the "nostats" boot option).

A nice idea came up on IRC:

| 10:31 < Guy-> make it an entry in the menu you display on successful boot
| 10:31 < Guy-> "submit anonymous boot report to grml developers"

Feedback and opinions as well as patches/implementation welcome. :)
