default settings for forumhome add-on

[Kseki]

couple requests/suggestions for after UPGRADE:

- make forumhome block YES by default for all but banned usergroup.
I have a lot of usergroups and going updating permissions one by one is a suuuuppper annoying.
- as such: reallly need a copy permissions to other usergroups feature.


- change wording for:

• Moderate this group's posts
• Moderate this group's images

so that if you click "all yes" it means moderation is OFF. (most people I assert prefer it off).

so eg:
- "moderation of this group's posts are disabled" or something


great stuff overall!!
