Check server for various interesting extensions.

	* providers/pop3/camel-pop3-store.c (connect_to_server): Check
	server for various interesting extensions.

	* providers/pop3/camel-pop3-folder.c (get_uids): If the server
	supports UIDL, use real UIDs rather than fake ones.
	(etc): Map uids back to numbers appropriately
