Spoike 776b8f6565 Added .dz playback support. 
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.
