ghodss/yaml converts from YAML to JSON before attempting to unmarshal.

* Use *json.RawMessage.
* Not have to support extravagant YAML features.
* Let our structs use `json:` tags
Instead of throwing a 500 error if a user enters an invalid name,

NOTE: An invalid username now returns much quicker than an invalid
password. Consider adding an arbitrary sleep in the future if we
care about masking which was invalid.
