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.
