/**
* This function is beign used to load info that's needed for the show_queue page.
* check if the person who wants to view this page is a mod/admin, if this is not the case, he will be redirected to an error page.
* if an action is set (this is done by $_GET['action']) it will try to execute it first, actions are: assign a ticket, unassign a ticket an create a queue.
* There are a few predefined queues which is the 'all tickets' queue, 'archive' queue, 'todo' queue, .. these are passed by $_GET['get'].
* if  $_GET['get'] = create; then it's a custom made queue, this will call the createQueue function which builds the query that we will later use to get the tickets.
* The tickets fetched will be returned and used in the template. Now why use POST and GET params here and have a createQueue function twice? Well the first time someone creates
* a queue the POST variables will be used, however after going to the next page it will use the GET params.
