q2 temp entity tweaks. still more work to be done.
support sRGB (mostly)properly in gl+vk+d3d9+d3d11.
vulkan tweaks - multisample works under certain conditions. additional other changes to comply... cvars to enable some other device extensions.
removed r_viewleaf. now using clusters for q1 too.
improved compat with quakespasm's sky command.
Added vid_winthread cvar, to handle window messages on a separate thread. When set this allows the game to keep redrawing when the user is resizing the window etc.
Finally added renderers option to menusys.

demo menu now properly lists the contents of archives.
demos played from subdirs/archives can now chain properly.
autodetect nehahra's demos. Add -nehahra argument to register/override cvar defaults (and set the right gamedir+startmap).
fix some q2 download bugs.
lame attempt at proper sRGB support (gl+vk+d3d9+d3d11 renderers).
fix q3bsp wrong-lightmaps bug.
match DP's viewzoom behaviour by not applying it when VF_[A]FOV was explicitly used.
fix d3d9 issue with missing textures screwing up blend modes.
vk: use a staging buffer instead of a staging textures per mip.
