DESEngine class

DES, ported from Bouncy Castle's DESEngine (table-driven, SP boxes).

Everything stays inside 32 bits: every left shift is masked with 0xFFFFFFFF, so the result is the same on the VM (64-bit ints) and when compiled to JavaScript (32-bit bitwise operations). The previous engine permuted bit by bit on 64-bit ints and gave wrong output in the browser.
