Fix "Couldn't create player_connect event" appearing on success
Apply some NPE checks to render data cache
Fix player model eyes pointing elsewhere when singleplayer is paused
Minor cleanup
Added vec = game.GetWindSpeed( vec pos = nil )
* Optional arg that takes into account wind controllers with radius above -1
* Without arg = only use the global controller (if one exists)
* position argument unfortunately will not do anything on client yet because the env_wind position is never networked to the clients
* Function is shared
