nqsv: added support for spectators with nq clients. the angles are a bit rough, but hey. need to do something about frags so nq clients know who's a spectator. use 'cmd observe' to get an nq client to spectate on an fte server (then attack/jump behave the same as in qw clients). nqsv: rewrote EF_MUZZLEFLASH handling, so svc_muzzleflash is now translated properly to EF_MUZZLEFLASH, and vice versa. No more missing muzzleflashes! added screenshot_cubemap, so you can actually pre-generate cubemaps with fte (which can be used for reflections or whatever). misc fixes (server crash, a couple of other less important ones). external files based on a model's name will now obey r_replacemodels properly, instead of needing to use foo.mdl_0.skin for foo.md3. identify <playernum> should now use the correct masked ip, instead of abrubtly failing (reported by kt) vid_toggle console command should now obey vid_width and vid_height when switching to fullscreen, but only if vid_fullscreen is actually set, which should make it seem better behaved (reported by kt). qcc: cleaned up sym->symboldata[sym->ofs] to be more consistent at all stages. qcc: typedef float vec4[4]; now works to define a float array with 4 elements (however, it will be passed by-value rather than by-reference). qcc: cleaned up optional vs __out ordering issues. qccgui: shift+f3 searches backwards git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5064 fc73d0e0-1445-4013-8a0c-d673dee63da5
