Subject: [PATCH] Ad-banners are now fetched in the given order

Ad-banners are now fetched in the order, that is defined in the variable
"zones". The work-queue "ads" is now stored in an array, because it is not
guarantied, that the JavaScript-engine iterates over the attributes of an
object in the same order, they were added.
