Use correct part of the Master-Key for generating encryption keys.
Before this change the IV-Key was used to generate encryption keys,
which was incorrect, but safe - for the XTS mode this key was unused
anyway and for CBC mode it was used differently to generate IV
vectors, so there is no risk that IV vector collides with encryption
key somehow.
Bump version number and keep compatibility for older versions.
