Added a hack to convert charsets in the format iso8859-1 to iso-8859-1

2001-07-13  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-mime-utils.c (rfc2047_decode_word): Added a hack to
	convert charsets in the format iso8859-1 to iso-8859-1 because it
	seems to be more iconv friendly. It has been reported that on some
	systems, iconv doesn't know about iso8859-1 while it *does* know
	about iso-8859-1. See bug #4530.
