Support TinderBox integration

The Syphon framework is copied to the build product via the `buildCopy` XML element, but requires [f7a0854a53](https://github.com/cinder/Cinder/commit/f7a0854a53a6f4d38ddb257944bf10088830c473) on the Cinder dev branch to recognize the destination setting of 'Frameworks' instead of the default 'Executables'. Users of earlier Cinder/TinderBox versions will need to manually change the destination in the 'Copy Files' phase in the 'Build Phases' section for their application target. See the forum topic [Canon SDK Block released](https://forum.libcinder.org/#Topic/23286000001862025) for more detail on the new `destination` attribute of the `buildCopy` element.
