Remove redundant signature check
E::Fs guarantees its representation is in the field, implicitly enforcing
that S < order(G).

SpendAuthSig.

Implement RedJubjub serialization
Also alters the Signature struct to store Rbar and Sbar instead of R and S,
to more closely match the specification.

bmerge dbe897d365 Auto merge of #79 - ebfull:nomorenightly, r=ebfull
Remove feature(i128_type)

The `i128_type` feature was recently stabilized in Rust, so this is unnecessary now for nightly users. In fact, in a few days there should be a new Rust beta (`1.26`) containing stable support for `i128_type`, meaning that (for Zcash) we can switch to the beta compiler for all future Rust development, and even switch to the stable compiler in six weeks when that's released.
