This commit distributes many of the various tests that were previously strewn about `test-crypto.js` into their own files, such as for Ciphers and Deciphers, Hashing, and HMACs. Copy pasta, and no style changes besides removing a few now-unnecessary closures. Helps eliminate file bloat and allows for easier test prognosis.
