Update password hash to use php password_hash by default

[mattlorimer]

Description

This updated user password hashing to use the new php password_hash implementation. This is greatly increase the security of user password stored in the database. It is fully backward compatible with previous password hashing, used in SuiteCRM, so should not cause any issues with users already using previous implementations of password hashing.

How To Test This

1. See that you can login to the application, api(s) using the existing password standard and backward compatible standards.
2. Update your password and see that it stored using the more secure hash and test that you can still login in all places.
