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.

fix q2bsp textures.
fix some vulkan validation issues.
MOVE_OTHERONLY is now an official feature (replacing MOVE_ONLYENT which is now removed, same functionality, better behaved behaviour).
network up edited brushes on initial connect. still needs more work for entity editing, but should otherwise be okay for now.
add sys_browserredirect console command for emscripten builds (can be used to trigger window redirections - including download requests)
