[For 1.8] Ban User List Page

[Sazze]

Works but:

1. Try not to hard-code the HTML, use the template system.
2. get_user() function is not something I'd use as it generates lots of queries (1 query per user). Check below, that's a query I use for my ban list.

$query = $db->write_query(sprintf("
	SELECT b.*, u2.*, u.uid AS id, u.username AS user, u.displaygroup AS dispgroup, u.usergroup AS ugroup FROM %sbanned b
	LEFT JOIN %susers u ON(b.admin = u.uid)
	LEFT JOIN %susers u2 ON(b.uid = u2.uid)
	ORDER BY b.dateline DESC
	LIMIT {$start}, {$perpage}", TABLE_PREFIX, TABLE_PREFIX, TABLE_PREFIX
));
