wrong type in Ext AS API of Ext.onReady()'s 3rd parameter
hack for create() function used for non-registered config classes:
the target contains the AS3 name, which in case of Ext is not the same
as the JavaScript name. As a workaround, replacing "ext." by "Ext.",
which is only half the truth. May have to change the [ExtConfig]
annotation parameter or the code generated from that.
When Ext JS is loaded via RequireJS, it has to be convinced that
documentReady already happened.
