Added some optional unsafe code (vectorised XOR) to stream ciphers - 20% to 100% (!) speed increase. Very fast.
Removed dependency on System.Security assembly (PBKDF2 and Scrypt used HMACSHA256 from it). Now uses all in-namespace cryptography.
Removed antiquated parameter class system, replaced with native datatypes.
Removed TripleDES, GOST 28147, and Whirlpool digest. All were too slow, and both GOST and TripleDES are simply inferior to other ciphers.
