Allow Team members (Admins) in Organizations to close feature requests

If a user has moderation rights or maybe even for users with push right, they should be able to change their projects feathub and close features.

Hmm, that's a good point. Upvoted!

At the very least an "Admin" with push rights should be able to manage feathub. I can do anything on the organization, but cannot manage/close feathub requests.

Done!
