relied on the old configuration values and old way of validating
passwords. Also improved registration page by always showing error
messages rather than hiding them on leaving the field.
the old validate password method and configuration values in favor of
AUTH_PASSWORD_VALIDATORS, a list of validators to use to check a
password. These include some that come straight from Django and some
that were written according to Django's specifications. This work also
included maintaining the current messaging as instruction text and
passing along restrictions for the password field.
Send password form instructions that include password complexity and
also send error messages back that include all parts of the
complexity instead of single parts at a time.
And clean up phrasing to be more consistent.
The password live validation was not considering the full password
complexity settings. This branch hooks that up and refactors the
various ways to validate a password to all go through the same code
path.
