2004-02-17  Jeffrey Stedfast  <fejj@ximian.com>

	Fix for bug #54060 (except for the "don't let users copy/move
	messages to Outbox" bit).

	* em-folder-tree.c (emft_drop_target): Rearranged a little. We can
	check for special dest folders right away. Also added a check for
	the default local folders (Drafts/Inbox/Outbox/Sent) since we
	don't want to be able to move them anywhere else (copying is ok).
	(emft_popup_copy_folder_selected): Don't allow moving any of the
	default local folders to be consistant with drag&drop changes.
	(emft_popup_rename_folder): Don't allow the user to rename a
	default local folder.
	(emft_popup_delete_folder): Don't allow deletion of special local
	folders.

	* mail-component.c (mail_component_peek_local_store): New function
	to peek the local store.
