Provides image loading capability for Java FX.

A plugin for loading a given format is added by creating an ImageFormatDescription to provide the principal attributes for recognizing images stored in the format, an ImageLoader which performs the actual loading of the image data and metadata, and an ImageLoaderFactory which is able to create an ImageLoader for a stream of image data stored in the format. The ImageLoaderFactory is registered with the ImageStorage object which manages all ImageLoaders and which also supplies convenience loading methods for application use.
