Added support for Emails, couldn't get any of the other examples to work
correctly. They kept causing Gmail to disable the account I was using.
Used example from previous capstone that I knew worked.

- EmailSender, NotificationDao, and STMPAuthenticator are used to send
emails. There is a method inside NotificationDao for approved
registrations which I believe is used on CoordinatorHomeView.

- ForgotPasswordController resets the password to Stonehill14 then sends
a notification that it has been changed to that and the user should
change it themselves once logged in.

- RegisterController now sends a notification that the registration went
successful and is under review.

- POM added dep. for email
