Expanding an error message.
We no longer need the SVGKImage extension in the OS X demo app.
Minor change that probably won't be relevant until later.
Use a macro in SKSVGKObject's accessors stating their unimplemented status.
Add a helper function in SKSVGBundleObject to get the file name sans extension and the extension.
Use the tertiary operator in startElementSAX
