Lfun:	query_def_ac - return the default armour class of a monster

Syntax:
	int query_def_ac()

Description:
	Via set_level every monster gets a default armour class depending
	on the level. The query_def_ac call returns this default armour
	class.

Return value:
	A positive integer indicating the armour class depending on level.

Examples:
	int ac;
	ac = monster->query_def_ac();

Note:
	Even when a monster wears armours, at least the default armour
	class is kept. Only if the added up armour classes of the worn
	armours are greater then the default, the added up armour classes
	are used.
