New usergroup stars

[Tim]

SMF doesn't automaticly select stars.gif when adding a new usergroup.
Infact, when adding it, it doesn't display any information on this. And when editing, I'm presuming to leave the file field blank and just fill in how many stars it should display. So I was quite suprised that no stars showed up, though it did say six when clicking on edit again.

Nitpicky, but still...
