Uses the extended Euclidean algorithm to calculate the multiplicative inverse, rather than a brute-force loop.

User can specify the alphabet to use. Some common alphabets are supplied in a menu.

For decryption, a new "use modular inverse" checkbox requires that the correct values for a and b must be supplied by the user, rather than calculated from the values used to encrypt.
