Filename case is not preserved on unpack.

Found this issue while searching clues for #4 .

With a repackaged .ykc from the original with no modified files, the game engine refuses to use the contained files and popups a missing file warning. Noticed that the path shown in the popup was having uppercase filename, I tried to batch-converted all related files (that were considered as missing by the engine) to uppercase, packit up again, and now it runs perfectly.

This might be a combination of few possible points:

• The engine itself is only recognizing case-sensitive filenames (ARGH!).
• YukaTool somehow ignored or can't recognized the filename case from the archive and just use lowercase for decompiled files on unpack. It's the same with YukaTool GUI, as the original .ykc, the repacked .ykc, and the fixed .ykc was showing the same, lowercased files and folders.
• YukaTool properly preserved the filename case on pack.

I've experimented with a simple directory with various cased files and folders, and it was clear that unpack isn't properly preserving the filename case, as in this screenshot:

I'll include the sample directory case (with various cased filenames) for easier analysis. test.zip

Here's the tree-list for the packed .ykc of the sample case, seen through YukaTool GUI:

The file name normalization was an intentional design choice, because I was fed up with the inconsistent naming used by some devs. I'm surprised this is causing any issues, the engine version I worked with accepted the lowercase files just fine.

Anyway, in release 2.5 I added the command line option --normalize-case=false to disable the normalization.
And while I was at it I also created a list command so you don't have to check with YukaTool GUI every time ^^

Thank you for the awesome help 😄 ! This would surely saves me a lot of headache.

Yeah, it's a surprise for me too, since normally they wouldn't want to tire themselves out regarding filename case in a complex game like this. I hope that this is just particularly specific to this game only, and not spread out to the rest of PeasSoft's other games.

Again, thank you very much for such a swift responses and assistance!
