Fixed for Bludit 3.0.0

Changes for plugin version 3.0.0 (aka fixed for Bludit 3.0.0 - 06/10/2018
amountOfItems now numberOfItems
$Language now $L - personally I'd prefer $Language, but keeping it in-sync.
$Url now $url
$Site now $site
$dbPages now $pages
$Login now $login
$pagesByParent now $parents
$pagesByChildren now $children

foreach ($staticPages as $pageKey) {	now	foreach ($staticPages as $page) {

Added checks for empty Lables - if (!empty($staticLabel)) {
added $staticPages = buildStaticPages();

Fixed the "Order content by" date to actually order by date, was previously only by position.

Removed "Admin Stuff" restriction for only Admin and Editors because Bludit 3 can't identify logged in user role.
