Spoike 4fcd615308 try to fix null framestates issue causing crashes from pmove/solid_bsp code. 
some tweaks to try to make webgl more robust.
added r_max_gpu_bones cvar. defaults to 0 in webgl for now (64 otherwise).
fixed gles2+skeletal issue that was breaking webgl (note r_max_gpu_bones needs to be set to 32 or something for it to actually use glsl bones with webgl).
sound rates now internally use decimals instead of percents. because meh.
allow PEXT2_MAXPLAYERS and angle deltas in nq.
