Moxie Marlinspike 741171c49f Switch to CBC mode with a derived IV. 
1) Since we're not CPU or space constrained (and are in fact
   padding), and since keystream reuse would be more catastrophic
   than IV reuse without chosen plaintext.

   with PreKeyWhisperMessages if the embedded WhsiperMessage
   fails to decrypt.
