fteqw/engine/server/sv_ents.c
Spoike e8aa715763 disabled some quake-only teamplay stuff in non-quake builds. 
GL: r_dynamic -1 is now r_temporalscenecache 1, which makes menu options etc a little friendlier. fixed a serious memory leak.
GL: Lightmaps are now uploaded using pbos to reduce cpu stalls (especially with temporalscenecache) and the resulting periodic framerate drops. Requires gl4.4.
PM: moved manifest-downloads to the package manager. still needs some proper testing.
PM: Fixed bug with downloading updates from every known mirror for that update.
PM: Fixed bug with duplicate mirrors...
PM: menuqc is now able to query available updates.
engine's Draw_TextBox centers the text box more appropriately and easily.
SV: added sv_autooffload cvar, when set the map command will automatically create a server in a separate process to reduce the effects of stutter in inefficient ssqc mods.
Menu: menu_mods now shares data with getgamedirinfo builtin.
MenuQC: Added some extra properties to the getgamedirinfo builtin.
MenuQC: Added Menu_RendererRestarted entrypoint.
MenuQC: _vid_renderer_opts cvar now has a value that actually reflects the windowing systems in the build, rather than just renderers.
CQSC: Added getlocationname builtin.
ALSA: device names are now more consistent with other audio drivers.
SV: added unsavegame console command, to delete unwanted saved games.
SV: hashtable entries are now saved into saved games.
SV: reworked player remapping strategy when loading games. Player slots are now directly swapped serverside, not reconnected.
SV: resend all csqc entity state when a client signals that it started recording a demo.
SV: Added SOLID_BSPTRIGGER as a shapely alternative to the aabb SOLID_TRIGGER. modelindex must still be set for this to work.
