Allow user to add or remove team members from a team space

At the moment, there is no way to add nor to remove team members from a team space blueprint

Steps to reproduce

1. Create a new team space blueprint
2. Click on Space Tools > Permission
3. Click on Edit permission
4. Add or remove user from the list.
5. Go to team space page. The user is not added to the team space nor removed.

Expected Behaviour
User is added in the team space automagically.

Workaround
Need to do it manually. Add another row or column to the table with the Profile picture macro and then add mailto-link macro below the profile picture.
