--unbuilt flag appears to do nothing.

Issue

Set up and build workspace:

rosinstall_generator --rosdistro indigo rospy --deps --tar > rospy.rosinstall
rosinstall src rospy.rosinstall -j8
catkin build --unbuilt
^C
catkin build --unbuilt

I would expect the second invocation of catkin build to pick up where the first one got interrupted (eg, as if --start-with foo had been passed), where foo was the first not-built package in the topological order, but in fact it starts from the beginning. I checked a few combinations of configurations and could find no scenario where the flag had any effect at all:

• Didn't matter whether the workspace included the catkin package or not.
• Didn't matter whether I was installing or not.
• Didn't matter whether I had set a whitelist or not.

All of the above do the right thing with --start-with.

@jbohren Curious for your thoughts on this.

This is way later - but I believe you also need --no-deps for this to work as you intended, otherwise it builds all of the unbuilt packages' dependencies.
