Remove sha2 dep; limit rand depends; fixes after PR#68 merge. 
* ADD new "batch" feature for feature-gating ed25519 batch verification; off by
   default. The "batch" feature is the only thing which depends on all of the
   `rand` crate, since it requires the functionality of `rand::thread_rng()`.
   Without batch verification, the rest of ed25519-dalek only depends on
   `rand_os` and `rand_core`.

Hardcode use of sha2::Sha512 in most cases. 
This implements https://github.com/dalek-cryptography/ed25519-dalek/issues/64

You can still choose the "prehash" algorithm, as long as it has 64 bytes of
output.  Otherwise, everything is hardcoded to use sha2::Sha512.  To use a
different implementation you'll need a [patch.crates-io] section in cargo
config.

Enabling std feature can now enable rand/std. 
Previously it pulled in a bunch of fuschia dependencies regardless of
target system.

Implement batch verification. 
The API for this isn't the greatest and I apologise for that.  Suggestions for
improvement welcome.  One thing which @hdevalence and I considered was to
change the function signature to:

    pub fn verify_batch<D, C, M, S, K>(messages: M,
                                       signatures: S,
                                       public_keys: K,
                                       csprng: &mut C) -> Result<(), SignatureError>
        where D: Digest<OutputSize = U64> + Default,
              C: Rng + CryptoRng,
              M: IntoIterator<Item = &[u8]>,
              S: IntoIterator,
              S::Item: Borrow<Signature>,
              K: IntoIterator,
              K::Item: Borrow<Signature>,

The other improvement which could be made is to implement 128-bit scalars for
the randomnesses.

030eff547f Make verify return a Result. 
This also simplifies the verification logic.  Because the verification check
happens in variable time, we don't need to do a constant-time eq check at the
end, so we can drop the `subtle` dependency entirely.

The `DecodingError` type becomes `SignatureError` and is also used to
signal failing verifications.
