How to record the Watchers and Followers we notify #19
Description
The user model should have a list of user IDs for their followers, and the game model should have a list of user IDs for their watchers. Then we can just have logic in our game controller that goes through a user's followers list to send notifications when a new game has been uploaded from this user or if a game gets a new version uploaded then its watchers should be notified.
On a user's profile page, we need a way for a user to start following this user. Maybe we add a star icon that is clickable and that will allow a user to start following this user. Similarly, we can have a pair of eyeballs that is clickable next to a game so that a user is notified of whenever this game has any changes made.
