	* camel-folder.c (camel_folder_copy_message_to): Don't allow the
	user to copy a message to or from the vtrash folder. Set an
	exception if they try.
	(camel_folder_move_message_to): This one is a bit more
	complicated: 1) If the user tried to move a message from the
	vtrash into the original folder, just undelete the message. 2) If
	the user tries to move the message to the vtrash folder, then just
	mark the message as deleted. 3) If the user tries to move the
	message from the vTrash to a folder other than the original, use
	the original folder as the source. As another optimization, I've
	made it so that if the user tries to move a message to the same
	folder, just no-op.
	(move_message_to): Unset the deleted flag before moving (assuming
	it's there).
	(copy_message_to): Same.

	* camel-vee-folder.c (camel_vee_folder_get_message_folder): New
	convenience function to get the folder from which the message uid
	is derived from.
