Image class and paths relative to classpath

Hi guys,

The JavaFX SceneBuilder will be able to deal easily with absolute
(eg, "file:/" or "http://") URLs, as well as with relative
("@...") URLs. However dealing with things like "classpath:/..."
will be more challenging.

The issue here is that 1. you need to define your classpath before
loading your FXML - so that the classpath:/ can be resolved, and
2. since you're editing an FXML you might not have anything in
the classpath yet - since you might not have compiled your project
yet. In which case what you'd need would be a sourcepath rather
than a classpath.

Although I do agree that classpath-based loading is interesting
at run time - it will make it difficult to deal with the file
at design-time - since it requires to set up some config before
you can load the FXML file. At design time, there's also the risk
that the wrong file will be loaded - e.g. that you will load
the obsolete copy of the file present in the build/ directory
instead of loading the brand new file you just dropped in your src/

On the other hand, using the @ notation usually works well both at
runtime and design time - which IMO makes it safer.
