Same idea here as with build_mesage(), don't convert th gconf charset

2004-04-15  Jeffrey Stedfast  <fejj@ximian.com>

	* e-msg-composer-attachment-bar.c (attach_to_multipart): Same idea
	here as with build_mesage(), don't convert th gconf charset
	setting to the iconv name before setting it on the mime part.

	* e-msg-composer.c (best_charset): Now returns a malloc'd string
	bufefr containing the charset that has NOT been converted to the
	iconv name. This is important in order to avoid using the iconv
	charset name which may or may not necessarily be the IANA blessed
	name.
	(composer_get_default_charset_setting): Changed to always return
	the actual value in the settings (eg. don't return the iconv
	name).
	(build_message): Updated for changes to best_charset(). Set the
	actual charset name as the charset param and then get the
	iconv_charset from that. Use iconv_charset everywhere else.
	(get_file_content): Updated for changes to
	get_default_charset_setting().
	(setup_ui): Same.
