This update brings with it a new feature of the regex crate which will now use SIMD optimizations automatically at runtime with no necessary compile time flags. All that's needed is to enable the `unstable` feature. Other crates, such as bytecount and encoding_rs, are still using the old-style SIMD support, so we leave the simd-accel and avx-accel features. However, the binaries we distribute on Github no longer have those features enabled, which makes them truly portable. Fixes #135

Pretty much what it says on the tin. This also brings in new AVX2 optimizations added in the regex crate. See: rust-lang/regex#456
We also employ the totally novel idea of updating the CHANGELOG incrementally, instead of doing everything in one swoop during a release.
Note that this does not move to
regex-syntax 0.5.0yet. That requires a bit more work.
