Feature: Profile Page

[miravuong]

Once users sign-up/log-in, there should be a link in the Navbar to the Profile page. It should appear on the Navbar as the user's profile photo (circular, generic if a new account).

The profile page should:

1. Display a jar with all the cookies the user bought on the Menu page.
2. Change first name, last name, email, password, and profile photo from profile page.
3. This page cannot be accessed unless a user is signed in.
