More fields needed to be added to each nancy game's entry in nancy.dat. Since this would've required bumping up the file version anyway, the opportunity was taken to rework its structure so future changes are smoother. The new format is based around sections, each with a tag denoting its contents, and an offset for easy skipping. Conditions for dialogue, goodbyes, and hints have an additional type field, with the newly-added difficulty type being required by nancy5's data. Data for sound channel types has also been added, since nancy4 and up changed the structure of the channel data. And lastly, files that were incorrectly using spaces for indentation have been switched to tabs.
