Don't bother with exists_changed. We don't need it afterall.

2004-06-12  Jeffrey Stedfast  <fejj@ximian.com>

	* providers/imap4/camel-imap4-summary.c
	(camel_imap4_summary_set_exists): Don't bother with
	exists_changed. We don't need it afterall.
	(camel_imap4_summary_flush_updates): Instead of updating flags if
	update_flags or exists_changed is set, only bother if update_flags
	is set or if exists is smaller than the summary count (since
	updating flags is also sueful for determining which messages have
	been removed).
