BCrypt/PHP's password_hash support

- added config var `use_password_hash`
 - added config var `password_hash_algo`
 - added config var `password_hash_options`
 - added `verify_password()`
 - changed `login()` (changed pass check with new the function, added a little skip for pass recreation if password_hash is active)
 - changed `hash_password()`
 - added `sql/Aauth_v2_BCrypt.sql` with a working password if BCrypt is active
