Made some slightly less uglier sprites for attack effects.dmi

Melee attacks, gun firing, and things being hit by bullets will now still give witnesses a message, but only if they are less than 3 tiles away. The attacker still doesn't get the message for its own attacks.

I added two arguments to visible_message(), one to specify the visibility range, and one to ignore a specific mob that shouldn't get the message.
