Image class and paths relative to classpath

An alternative to the separate method is to define a 'classpath' protocol as part of the URL:

Image image = new Image("classpath:/foo/bar.png"); 

This is common in Spring and seems quite nice to me. It has the advantage of working with constructors and is fully backwards compatible. 

I could live with a new method if that was the preference though.

So Image.fromClassPath("duke.jpg") called from myapplication.Application will look for the file in myapplication package.
