		210	Many objects in crossfire are so-called attachable objects. That means you can
		211	attach callbacks/event handlers (a collection of which is called an "attachment")
		212	to it. All such attachable objects support the following methods.
		213
		214	In the following description, CLASS can be any of C<global>, C<object>
		215	C<player>, C<client> or C<map> (i.e. the attachable objects in
