fix crash from qwplayers with invalid modelindexes rework allow_skybox a little. now applies immediately. try to fix the appears-outside-of-map bug, again. dir *.wav now shows a little extra info on mouse-over. try loading music file extensions that we expect to be able to play via ffmpeg, not just the ones that are directly supported. rework the hidden fps_presets, show them with tab completion. fix a possible crash with r_temporalscenecache fix lightmap updates on submodels not happening properly with the scenecache. fix the serious memory leak with scenecache. add r_glsl_pbr cvar to force use of pbr pathways in our glsl. fix bug in alsa output not supporting float output properly. preliminary work to have the mixer use floating point mixing. disabled for now. try to update sys_register_file_associations on linux, still needs work though. try to work around nquake's config quirks, so config files don't get overwritten. repackage quake's conchars in order to add padding. this should avoid extra junk on the outside of glyphs. give fteqcc(commandline version) some extra package extration/creation support. our paks should be more end-user-friendly, and our spanned pk3s are awesome. write rune state to legacy saved games, so we don't ever have the missing-runes bug ever again... git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5780 fc73d0e0-1445-4013-8a0c-d673dee63da5
