Show indirect changes for projects

[tengstrand]

When a project has changed (one or several files in its own project directory) a * will follow the project name when running the info command. If no project files have changed, no * is shown today, even if the project is indirectly changed by one or several of its (changed) bricks.

An improvement could be to show + if the project is indirectly change (but keep * if only the project itself has changed). This could be used to get a view of which projects to release, by sending in since:release (or some other :tag-patterns key).
