Ref T1049. Adds bin/harbormaster and bin/harbormaster build for applying plans from the console. Since this gets --trace, it's much easier to debug what's going on.
This doesn't work properly with some of the Drydock steps yet, I need to look at those. I think setRunAllTasksInProcess probably obsoletes some of the mechanisms. It might also not work with "Wait for Builds" but I didn't check.
