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.)

Support for Additional Cryptor Modes

This release add support for more cryptor modes. See PR #29 for details.
