add (X)Salsa20/r
ChaCha20 (and ChaCha8 + ChaCha12)
add sjcl.bitArrayLE
add SHA3 (Keccak)

Export only sjcl.hash.keccak-{224,256,384,512} with parameters based on
Keccak submission for SHA3, which may not be the final parameters.

Also SHA3 will probably add more "padding" (Sakura, domain separation).
