* More descriptive reason for "to many requests" when registering
Currently the only way for a user to get a response of "to many registration attempts" is by the servers configuration to restrict the number of registration attempts but the error message presented to the user is very vague as to why they have been denied. This PR updates the reasoning. I'm open for suggestions on any clarity recommendations.
* Added more clarity
Updated error message to include email address information for even greater clarity.
