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`.
