Title: SSE, Vector Tests, and PHP Similarity

Added the SSE version of scrypt, as it is significantly faster, and added configuration checks to switch between the two. Also added compilation tests to make sure test vectors work properly. Finally, all PHP hash functions output in hex and have an option for raw_output. It is probably best to comply with what is already the standard.
