Make superdevmode work with vaadin-archetype-widget

Currently if I create a project with vaadin-archetype-widget it is too difficult to run superdevmode.

What I'd expect to work is:

1. Run mvn clean install on root
 project
2. Run mvn jetty:run on widget-demo
 project
3. Run mvn vaadin:run-codeserver on widget-demo project

This does start up the superdevmode and it appears to be working but actually it does not notice client-side code changes in the widget project. I guess this is because it's using sources from the artifact in the local repo.

You can create an additional maven profile and include the sources from the widget project but this should happen automatically. Or at the very least document at vaadin.com/maven how to do this.

The same should be done for j2ee, spring, and multimodule artifacts.

There is a way to do this in the eclipse by running the SDM as a custom maven launch. You need to select "Resolve workspace artifacts". This thought depends on the jetty running with a compiled widgetset. After this the changes made in the widget module are seen upon reload in the UI.
