Forumlar / Cotonti / Core Labs / Archive / Hidden Groups Issue

Should be configurable I think:

- Hide group name only (current method)
- Hide users in userlist when their main group is hidden (should be default)
- Hide users in userlist when any of their subgroups is hidden

What goes for userlist also goes for whosonline plugin.

Now the question is to make this configurable site-wide, or per group. Obviously the 2nd option will require an extra db column in cot_groups and a lot more code too. I think site-wide will be flexible enough.

I think we should take out the current implementation of hidden groups and rewrite it in a plugin.
