	* providers/imap/camel-imap-folder.c (imap_update_summary): Sort
	the needheaders UID array and fixed to respect the
	UID_SET_LIMIT. This should now finish the fixification of bug
	#2529. There's still the possible issue that a command-line (The
	only command-line I can think of that can still be too long is a
	SEARCH command, but this can't possibly be fixed until we rewrite
	the imap code to use Zucchi's ImapEngine idea).
