Fix obscure error in Animated Doors where the Actor can be NULL

Browse source 
This is a quick fix for an error in which Animated Doors crash the game by trying to check "actor->player" when "actor" itself is NULL.  Deleting the check entirely also worked, but I worried it might be there for some higher-level scripting reason.  This just puts in a check to make sure actor isn't NULL before checking actor->player, and keeps the behavior in that case the same.

I think this was happening because I had doors being opened by projectiles (like in Metroid) which were being despawned into NULL pointers when they hit the doors, as this was an issue when initially programming said doors..
