Fixes bug #1717.

2003-12-11  Jeffrey Stedfast  <fejj@ximian.com>

	Fixes bug #1717.

	* em-folder-browser.c (emfb_list_built): If we have a uid to
	select, select that instead of selecting the first unread.
	(emfb_set_folder): CamelObject::meta_get() actually returns a
	strdup'd buffer, so we need to free it. Get the last selected uid
	and set that up as the uid to select when the message-list
	finishes building.
	(emfb_list_message_selected): Save the selected uid.
	(emfb_init): Connect to the message-list's message_selected signal
	so that we can save selected state (don't want to do this in
	EMFolderView or MessageList because we don't want the state to be
	saved for the EMMessageBrowser).
