Changed how cubemaps are held in memory, making all images basically just 3d textures.
Don't start up at all if no game data is found.

openal: doppler now applies to openal more consistently.
vulkan: vk_loadglsl cvar enables vk_nv_glsl_shader, with support for existing glsl shaders (still no permutations for now). needs !!samps stuff.
vulkan: r_renderscale now partly works. r_fxaa also works under specific circumstances. needs more work. still no bloom or projections stuff.
menu_download: got a few tweaks to improve it, including zips. I still want to handle engine updates with this stuff, but that can wait for later.

setcursormode now available to menuqc too. this gives menuqc hardware cursor support (useful to revert some braindamage I added for dp compat - menuqc is a dp spec).
