Shrinkwrap output visualization

When writing packaging descriptions (e.g. via Shrinkwrap or traditionally via Ant/Maven), you often want to view what the generated artifact looks like so you can check where a particular file is placed.

Provide a visualization of the current Shrinkwrap, this should view just like the package explorer in eclipse (consistency!) and update in realtime as someone alters their shrinkwrap declaration. Having a filter would be useful as well.
