Spoike 934a97c53e fix some compile issues (errors and warnings). sdl, ode, vulkan.
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)
