Title: Hashing improvements

* Added HASH_VERSION to interchange hashing systems for pins/passwords
* Added pepper as a salt hash into the final hashed string in the password/pin coloum

This will make adjusting the hashing systems at least feasible for new accounts and those that changed their password and/or PIN to the new system. A simple password change or PIN reset will do the trick.
