This PR does not fix apps/ project.  In fact, I think .project in apps/ should be removed, and instead we should create individual projects, either for a group (i.e. samples, toys), or for each application (i.e. Robot, 3DViewer).

This work depends on  the cleanup.  We could probably do it in a separate bug.  What do you think?
