Upgraded aescrypt to use the standard reference TwoFish implementation, 'cause I got tired of trying to figure out the Endianness in Dr. Gladman's code.

Mostly moribund for the past month, as I've been busy working on mtx and the Linux tape drivers.

No key generator yet, 'dd if=/dev/random bs=512 count=1 | md5sum' will give you a random key that you can massage into a key of the correct format (see file 'key' for the format).
