This change does not complete the work to handle snapshots correctly, but it does implement the behavior of re-building the snapshot on each file invalidation. It also moves to the approach of caching the FileHandles on the snapshot, rather than in the goFile object, which is now not necessary. Finally, this change shifts the logic of metadata invalidation into the content invalidation step, so there is less logic to decide if we should re-load a package or not.
