Linux gnome crash workaround

[drojf]

This option adds a workaround for the "Linux Gnome Windowed Mode Crash" bug

---

For info on the Linux Gnome Windowed Mode Crash bug, see:

• Linux GNOME desktop environment crash / corrupted configuration file issue #97

This PR does not fix crashing when entering Windowed mode, but makes sure that you can't get the game stuck in a state where it won't launch anymore due to being in Windowed mode (it should recover and enter fullscreen mode). The main things this PR does is:

• Add a "full screen lock" option which prevents you accidnetally entering full screen mode., plus a setup menu to tell the user to configure it on Linux
• On Linux, if the game crashes, will revert to fullscreen mode, and will re-display the "full screen lock" setup menu
  • Note that I can't detect crashes that well, so force closing the app is equivalent to a crash
• Force the playerprefs "Screenmanager Is Fullscreen mode" to always be 1 (fullscreen) instead of 0 (windowed). We used to always force the value to 0.
• Change how/when the playerprefs is saved
• Refactor stuff internally so that the screen resolution and windowed/fullscreen mode boils down to exactly one function, rather being called differently from lots of different places

I've primarily tested on Windows and Manjaro Linux (The system which a user had reported these issues), but I should probably re-test Ubuntu to see if I have broken anything. Some of the changes I made are locked to Linux, to avoid changing working behavior on Windows, but the refactoring and stuff is across all OS's, so that could break things.

@TellowKrinkle reported that this resolution bug only happens on the 64-bit version of the game - the 32-bit version is unaffected.

For me to run the 32-bit version of the game on Manjaro (based on Arch Linux)I needed to install:

• lib32-libxcursor
• lib32-libxrandr

I think I'll keep the recovery menu/first time linux windowed mode setup menu, but add a note on the first-time setup to run the 32 bit version / link to the wiki with instructions on how to run the 32-bit version, if you have problems with crashes.

Should also update the fullscreen-lock button hover-over with this information.

Okay never mind it's still kind of broken, just not as broken
Here's the broken function
Notice anything funny?
If the global variable is initialized, it doesn't call XGetWMNormalHints to initialize the stack variable
They probably meant to pass the global variable to XSetWMNormalHints
But they passed the uninitialized stack variable instead

The proper patch would be to pass global pointer
But the lazy patch is to nop out the assignment so the global pointer is just always null
Here's a patched Higurashi 05 exe

game.zip

Uhh actually before you add it to the installer, we should verify that there aren't multiple Higu05 exes around
The exe that's based off of has the sha 09f15d361d7556943dab3a1393ccf0ff7af42082
(Side note, I'm fairly sure exes are fixed unity things and not per-game, which means that's a unity bug that affects all unity games on that version. Changing the screen size more than once sends garbage to X11 on all Unity Linux builds of that version)

However, there may be a couple commits I want to keep from this pR, so please don't close this PR yet
