Add Following tab to the user profile view

[wippo-devops]

Closes #1447 All of these tasks should be done in the accounts app.

Description

Created a new view that shows followers of user (/profile//following). View shows clicable image icons of profile pictures of followers. If there are zero followers it shows message that no one is following.

I was thinking it might be good idea to add this to profile below the "About me" section, but it was not mentioned in the issue.
