[Feature Request] Allow a default email address to be specified in AuthUI.IdpConfig.EmailBuilder()

[avoirtech]

It can often be the case that the calling code will have a good idea what email address the user is going to use to sign in with (for example, when resuming after sending a verification email).

It would make things smoother for the end user if we could have a method to pre-populate the email address field in the email sign in page. Something like:
AuthUI.IdpConfig.EmailBuilder().setEmail("[email protected]").build()

@avoirtech thanks for this! Sounds like a nice improvement.

Is there a way to get the password the user used to sign up? Because it is needed since FirebaseAuth.getInstance().signInWithEmailAndPassword(strEmail, strPassword) requires it, and FirebaseUI doesn't provide this functionality.

Adding the feature of this issue would be more than just a nice improvement.

@danielfaust no there is currently no way to get the password the user signed up with. Can you file a new issue explaining what you're doing that would require this?
