[Cooker] User creation in DrakX.

[Mattias Dahlberg]

Now when I installed Mdk8 for the 10th time I promised myself to share a 
suggestion with you: Could you please make the user name suggestion optional, 
with a checkbox or something like that? Everytime I write a real name I have to 
erase the entire suggested user name and replace it with my own. A checkbox or 
a button saying "suggest" or whatever, please.
