small typography change
\CommonBundle\Entity\User\Credential doesn't have a getCredential() method
Changed constructor of Credential
Now takes $credential [, $algorithm [, $iterations ]] instead of $algorithm, $credential [, $iterations]
Credentials can now be updated, update is applied at login
created shouldUpdate() and update() to the Credential, moved hashing to separate method instead of separately in three different methods
shouldn't have committed that line...
Small fixes
Some CS changes
