replace all Ext.Ajax.request calls with window.doAJAXRequest calls

Created by: bwbohl

Edirom Online has a own AJAXController defined in AJAXController.js, the benefits of using it are e.g. that the edition [editionId] is always submitted as parameter in those request calls. Although considered the ‘new’ way of doing AJAX requests in Edirom Online this has been in place for years but never thoroughly implemented on project scale.

Consequently Ext.Ajax.request calls should be considered deprecated and replaced everywhere.
