Stronger password validation, and a new Validator that auto-plugs your password checker strategy.

This release adds Zxcvbn password checking, a number of validation improvements, and starts the road toward PHP 7.4 with strong typehints, losing the 7.0 annotation baggage.

The added typehints have allowed me to relax some checks for weakness here and there.

This release also adds user-bound api tokens, a bin-packed uuid that you can use as a part of your external authentication needs.
