Support application icon

[puce77]

Support setting the application icon declaratively.

Should this be implemented as a custom extension point with a custom annotation? Or as part of the Maven plugin? Or do we have to wait for this until we have proper packaging support (native, Java Web Start,...) as those will use icons as well?

Personally I would make it a extension point for the UI. My main argument would be that the running application might need to provide icons for the window and the dock (on OS X). That can be easily covered by an extension point. The packaging of the application is another "separate" issue. The icons that are used for the packaging are independent from the scene icon (not as a resource but as a programming aspect). One has to be defined by code and the other by the packaging tool. That is my small opinion on it :)
