* mail-account-gui.c: Changes to allow combined store/transport
	providers (like exchange and nntp). You can only select the
	transport if the account is also using that provider for the
	source.
	(source_type_changed): If changing away from a combined
	store/transport type, disable that provider on the transport page.
	If change to a combined store/transport type, enable and select
	that provider on the transport page.
	(mail_account_gui_setup): Do some additional bookkeeping here to
	make the above stuff work.
	(transport_type_changed): If the provider is a combined
	store/transport type, pretend it doesn't need any additional URL
	configuration.
	(mail_account_gui_transport_complete): if the transport provider
	is also a store provider, then as long as it matches the source
	for the account, it's considered complete.
	(mail_account_gui_save): If the selected transport is a combined
	store/transport provider, use the source page's information to
	fill in the transport url.

	* mail-local.c (mail_local_provider_init): Don't set up
	service_cache.
