Converted the 'start' event into 'done' event in the resolved configuration builder. I need to know when we're done building so that we can flush the results to disk.
Fixed an issue introduced in an earlier commit (reordered the arguments in one method for some reason).
Refactored the signature of one of the methods for better clarity.
Added some initial types for the next big feature: on-the-fly serialisation of the dependency results.
