new parameter to e_passwords_init, and add prototype for

2001-10-12  Chris Toshok  <toshok@ximian.com>

	* e-passwords.h: new parameter to e_passwords_init, and add
	prototype for e_passwords_clear_component_passwords.

	* e-passwords.c (e_passwords_init): copy off the component name.
	(e_passwords_shutdown): free/NULL the component name.
	(e_passwords_clear_component_passwords): new function.  remove the
	subtree rooted at /Passwords/<ComponentName>.
	(e_passwords_remember_password): use component_name when building
	up the path.
	(e_passwords_get_password): same.
	(e_passwords_add_password): remove/free the currently stored
	session password for this key if there is one, before adding the
	new one.
