Implement Email Password Authentication Method

[letsintegreat]

Right now, there is only one method to authenticate - Google. Implement Email Password method of firebase, so users can login with custom email and password.

• [ ] In Login Screen, add another button.
• [ ] You have to create two pages for Log in and Sign up separately. As you can see in the User Model, we also need the name of the user, so take name as an input from user in Sign up page.
• [ ] Take the inspiration from Google auth code, and implement the logic of adding the user to the Firestore database, when the user creates a new account.
