[IMPLEMENTED] Limit to number of groups each user can create


I see the option to limit the number of forums that can be created per group, but not any way to limit actual group creation to a specific number. I'd like to limit the number of groups users can create in each category to prevent (or at least limit) abuse. For now I've set the categories to require moderation approval before they're public, and restricted group creation to a usergroup that we auto-assign to users once they've been registered for at least 1 day (along with a few other spam/abuse prevention permissions). However, that doesn't prevent a large number of spam groups from being potentially created by a single user, even if they're initially hidden.
