[Camera Plugin] Add support to save unmodified image to photoalbum

[Stephan Wezel]

Hi,

for a project which I'm developing with cordova i need the possibility
to save the unmodified image from the camera to the photoalbum.

I have attached a patch which implements this new functionality for iOS.

Regards

Stephan Wezel
