Remove deprecated identifiers (those using the pasteboard/mac address)

Removes the deprecated identifiers from the SDK. This clears up the remaining warnings relating to building for 64 bit architectures, so I was able to turn on "treat warnings as errors".

Tested the following things:

- [x] Builds the SDK from the build script
- [x] Unit Tests pass
- [x] Integration Tests pass
- [x] iOS 7 32 bit builds
- [x] iOS 7 64 bit builds
- [x] iOS 6 builds
