Updated to check for EXPUNGE notifications

2000-08-29  Jeffrey Stedfast  <fejj@helixcode.com>

	* providers/imap/camel-imap-store.c (camel_imap_command_extended):
	Updated to check for EXPUNGE notifications

	* providers/imap/camel-imap-folder.c (camel_imap_folder_changed):
	Updated to account for messages which have been expunged (now
	takes a new arg, a GPtrArray of message id's that have been
	expunged)
	(imap_expunge): Updated (we may want to just use the code in
	folder_changed now instead of doing our own summary
	expunging...but that can be fixed later)
	(imap_append_message): Updated.
	(imap_copy_message_to): Updated.
	(imap_move_message_to): Updated.
