Script Summary: Shows mutual friends module box when visiting a user's profile.
Facebook-style display of mutual friends. The new module box will be displayed above Friends. When a user's profile page is opened, a link to load mutual friends is displayed. Clicking the link will load and display all mutual friends.
The script fetches all Friends' pages of both signed in user and a user whose profile is being viewed and does not cache any result. Hence, mutual friends list is not automatically retrieved on page load.
