Support iOS Assets Directly

Before, you could not upload a photo asset file directly (they started with 'assets-library://'). You had to convert them into a temp file. That was handled by 3rd party libraries but some people needed to upload the asset directly. Now you can!

Upload a file starting with 'assets-library' and the iOS module will upload that. Internally it creates a copy of the asset in a temp file, which is required by the system in order to upload.

Have fun!
