Lfun:	set_brave - make a monster very brave and not wimpy at all

Synopsis:
	void set_brave(int brave)

Description:
	The set_brave call makes a monster more than NOT wimpy, which
	means it won't run away, even when the lfunc run_away() is called.

	This is useful against clerics of Axelrod's Guild and perhaps
	others. Monsters with set_brave(1) could not be scared away. No
	overloading of run_away() needed by setting up an extra object by
	using inherit. Especially for monsters which walk a fixed way or
	should stay in place.

Return value:
	none

Examples:
	monster->set_brave(1);

Note:
	Creating tools for players to change the braveness of a monster is
	prohibited. Setting an existing brave monster to not being brave
	and calling run_away() is NOT allowed. If the creator of a monster
	says it is brave, then it IS brave! With your own monsters you can
	do what you want e.g. also changing their braveness ;-)
