Spoike 845bb231ca xonotic: fix 'sticky walls' issue when spectating. 
xonotic: fix jumppads not working while onground.
attempt to parse meag's protocol changes, in case we get a .qwd from ezquake. does not report them to servers at this time.
added cl_fullpitch cvar. only affects nq servers that lack serverinfo.
support dds/ktx-based cubemaps, including for skyboxes.
recognise multiple new compressed texture formats - bc1-7, etc1+2+eac,.astc. Addeded to supporting drivers/apis.
software decoder for etc2,bc4+bc5 textures, so they can be considered universal (but with fallbacks).
software decoder for bc1-bc3 textures, but disabled due to lingering patent paranoia.
report heartbeats once, by default.
r_viewmodel_fov support for vk+d3d9+d3d11 renderers.
fix depth projection differences with various renderers (min dist is now consistent).
added some code to announce when cl_delay_packets changes.
