Adding in support for non-windows OSes for Simitone

[alexjyong]

Some updates I had to do to get Simitone to work on Linux. (Unfortunately, was not able to test on macOS)

I have done testing on Ubuntu (through WSL) and Linux Mint (through QEMU)

Currently have this implemented in Simitone on the unix-support branch. If this is merged, I'll update this branch to point at the new commit in upstream FreeSO instead of my own.

All changes seem reasonable. I'm surprised I didn't run into the directory structure not handling case insensitivity before.

I wonder what the performance impact of this is (not that I can think of a good way around it). It's entirely possible that it also tries a case insensitivity check on a bunch of directories outside the game directories, eg. /home/user/games/The Sims/... would always check home, user, games and The Sims. On some platforms, you might not be able to enumerate directories outside of a container (iOS has issues with this, maybe flatpak). Maybe Insensitive(..) could know about the base path and skip checks for those directories.

I have noticed that the Linux version takes a bit longer to start up and there's a bit of an audio stutter at start up (goes away quickly though), but game play is otherwise normal.
