Coinbase backend defaults to 'balance' but the complete calls user_data with looks for /users api path

[elgreg]

oauth calls do_auth which tries to get user_data, but if the default scope of 'balance' is used for coinbase, the /user path is denied. Not a huge deal, but made getting started difficult. Perhaps consider using 'user' as the default scope or using the 'balance' endpoint?

@elgreg, I've added user to default scope list, kept balance there for backward compatibility. Thanks for the report.
