vkQuake 1.31.1 Binaries

A worthwhile update over the last version, especially for the fixes.

As usual contributions came from either Quakespasm or Ironwail in addition to our own.

Improvements:

• Windows binaries : added the version number in the executable Properties
• Removed option Game > Load last save = fast, replaced by the addition of Game > Fast loading = on/off applicable to all loading actions:
  With Fast loading = on, loading the same level over and over become almost instantaneous, even for monster levels like The Immortal Lock.
• Library updates
• Code cleanups

Fixes:

• Various Linux build fixes (makefile)
• MiNGW/MSYS2 executable missing icon
• Moving Elevators hurting player and monsters, with fixes by @andrei-drexler (sv_gamefix_elevators CVAR) and others
• Remove Sky_ClipPoly: MAX_CLIP_VERTS hardcoded limit
• Sound resample compute can overflow with very big sounds
• Erroneous Vulkan usage crashing MacOS (MoltenVK)
• Host_error: ed_alloc: no free edicts due to edicts "leak", showing up on big levels in particular.

Special thanks to @j4reporting (and others) for support, testing and suggestions.

Please note: Windows 32bit binaries are not tested / not supported and are provided "as-is".

Windows binaries require the Microsoft Visual C++ Redistributable:
https://aka.ms/vs/17/release/vc_redist.x86.exe (32 bit)
https://aka.ms/vs/17/release/vc_redist.x64.exe (64 bit)

Linux AppImage requires at least glibc 2.31. Check with ldd --version if in doubt (any recent Linux distribution should easily satisfy this). FUSE must be enabled and available (see https://docs.appimage.org/user-guide/troubleshooting/fuse.html)
