fix #71
Signup and login page are both rendered in LoginModal.js. The login state in LoginModal.js determined whether login or signup page was rendered. By default it was always login.
I took the login state and put it in AuthContext so that we can specify whether login or signup is the default view rendered when the login modal pops up
