Add a way to get a list of used resources in a scene

[mrDIMAS]

This could be very helpful to find unused resources in a project. There should be a new menu Scene with Show Used Resources item in it, that will open a window with a text box that is filled with unique paths to used resources in a scene.

This is done. You can find your scene in Asset Browser, right-click on it, select Dependencies and a dependency graph will be built.
