This change disallows creation of users possessing the same email.
If a user attempts to create an account with an email address
that's already used - whether it belongs to an active account or not -
he will be notified of unsuccessful account creation. If he attempts to
log in using an email address belonging to an inactive account,
he will be presented with a link allowing him to re-send the
verification email. Attempting to register with an email address
belonging to an existing account triggers a password reset email.

Provides the means to serve an error to the user with a user-friendly
error message (serveCustomJSONError). Auth API uses this when
processing registration attempts.
Previously, the error message was inferred by the client based on
the status code of the response received from the server. However,
if multiple distinct errors fit a certain status code, it was impossible
to correctly interpret the error.

This change removes all the separate implementations for
`apiservice.serveJSONError()` and defines one for every service to use
in `consoleapi/common.go`.
