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. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5008 fc73d0e0-1445-4013-8a0c-d673dee63da5
