New GGST config, fast config updating feature

This new version updates the GGST config and adds a feature that should massively reduce the work required to update a game config to the latest version.

The new feature, config-size-update, requires another config with an updated list of instructions and their sizes, and once given that and the old config, it automatically merges the data into the old config, so you preserve everything already added, while merging any new changes. BBScript should be updated for new game releases much more consistently now!
