Build Notifications system

[tobyzerner]

_1 Upvote_ Flarum's core will need to have a notification framework in place for extensions to make use of.

This should be loosely based on esoTalk's notifications/activity model. You can read about how that works in the esoTalk documentation. Also, the esoTalk source is well-commented — take a look at that if you are interested in this.

I’ll write more about this as it becomes more of a priority.
