cd376996cdb3 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.

23c62e28b3a4 Reworked symmetric cipher classes to have SymmetricCipher as their superclass, and follow the general interface of init(), process(), etc. Made sure everything still passed test vectors. Removed Cipher class. I'll worry about that shit when we support something other than symmetric ciphers.
