support for posting both to mail and to (multiple) folders

2004-01-12  Meilof Veeningen  <meilof@wanadoo.nl>

	* em-composer-utils.c: support for posting both to mail and to
	(multiple) folders

	* em-folder-browser.c: use em_utils_post_to_folder (works with NNTP)

	* em-folder-selection-button.[ch]: added multiple selection mode

	* em-folder-selector.[ch]: idem

	* em-folder-tree.[ch]: added multiple selection mode, no longer show
	disabled accounts

	* em-utils.c: various changes to allow posting to (multiple) folders

	* em-subscribe-editor.c: double-clicking a node in the editor updates
	it directly

	* mail-ops.c: for appending messages, set the "X-Mailer" header
