		152	Many objects in crossfire are so-called attachable objects. That means you can
		153	attach callbacks/event handlers (a collection of which is called an "attachment")
		154	to it. All such attachable objects support the following methods.
		155
		156	In the following description, CLASS can be any of C<global>, C<object>
		157	C<player>, C<client> or C<map> (i.e. the attachable objects in
