Xcode 8 and Swift 2.3 Support
This release adds support for building using Xcode 8 (in legacy Swift 2.3 mode).
It is still possible to build in Xcode 7.3.1 too hence only bumping version from 0.8.0 -> 0.8.1.
There are not source changes associated with this release, it is all build file changes (specifically the Xcode project and the .travis.yml
file.)
