This could lead to passwords being attackable in case someone gets access to the raw data stored inside the database. This commit introduces password hashing using bcrypt hashing function which addresses this issue. Old passwords are not automatically re-hashed as they are unknown. Replacing the old password scheme is not that easy and needs #10 to be solved. Therefore the old hashing scheme is kept for compatibility reason.
