Give the full path of the wax-seal icons. (try_inline_pgp_sig): Convert

2001-09-07  Jeffrey Stedfast  <fejj@ximian.com>

	* mail-format.c (mail_write_authenticity): Give the full path of
	the wax-seal icons.
	(try_inline_pgp_sig): Convert the charset from UTF-8 to whatever
	charset it should be. Now takes a CamelMimePart argument as well.
	(try_uudecoding): Now takes a part argument as well.
	(try_inline_pgp): Here too.
	(try_binhex): And finally here.
	(handle_text_plain): Pass along the mime part to the try_*
	functions.
