Changed hardcoded encryption mode from AES256-CBC to AES256-CTR. Added blowfish encryption algorithm code. MPINT: Improved multi precision math routines. Variable length MPINTS, leading zeroes allowed but not nescessary. Other bugfixes. Added tests vectors for MPINT routines. git-svn-id: svn://kolibrios.org@9070 a494cfbc-eb01-0410-851d-a64ba20cac60
