Renamed SymmetricCipher back to Cipher (we don't support any other kind atm, I'll deal with it when we do.). Added BlockCipherWrapper for the encryption of arbitrary streams with or without padding. Removed hashByName, and replaced it with createHash. Re-did the high-level API, and filled out Crypto. Added cipher creation via createCipher. Added dsk to the CONTRIBUTORS file for helping with the design of the high-level API.
