Print message when having an asthma attack.

Problem introduced here: http://smf.cataclysmdda.com/index.php?topic=601.0

With the automatic usage of the inhaler, the player would never know they had an attack. In fact, the asthma attack is only visible when the player has no inhaler, is under water or sleeping. This leads to the observation that asthma occurs only during sleep.

The added message makes the ("harmless") asthma attacks visible.

I know, string freeze, but maybe later.
