Mural and network refactoring
Now that private notifications are properly handled but the wall and network are accessible to every follower. This makes no sense since being a follower is should be related with receiving notifications about the profile and not being able to see the wall or network. Also with access to the wall, anyone can post anything. So I'll:
- Add an option on profile to define who can access the wall (Logged users, Members or Administrators).
- Restrain access to post on the wall only to members/friends.
- Networkk is only accessible to the user himself/herself.
