Convert users of {MD5,SHA1,SHA256,SHA512}Summation to use Hashes

This makes use of the a function GetHashString() that returns
the specific hash string. We also need to implement another overload
of Add() for signed chars with sizes, so the existing users do not
require reinterpret_cast everywhere.
