Added a patch for a softlock between day 2 and 3, as well
as one at the very end of day 3. Added a patch for a buggy
scene that won't work properly without subtitles. Both of
these patches are supposed to be distributed by HeR, but
the file on their website does not actually contain them;
thus, they're both homebrew.
Added code for reading .cif files, and combining them into
a ciftree, which is then to be written to nancy.dat. Removed
the nancy2_patchtree binary file, and added the four source
files in its place.
Added facilities for embedding game patches into nancy.dat
Added two game patches for nancy2:
- one of the original patches, as distributed by the original
devs. Specifically, only the patch to extend the end-game
timer; there exists another patch that fixes an error when
double-clicking a specific cupboard, but that's caused by
an engine bug that does not exist in ScummVM.
- a new, custom patch that fixes a nasty softlock caused
by incorrect dependencies in a certain scene.
