[flexcoders] Inject dependency into Flex application preloader

[method_air]

Is it possible?

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009";
                           xmlns:s="library://ns.adobe.com/flex/spark"
                           xmlns:mx="library://ns.adobe.com/flex/mx"
                           
preloader="com.storefront.editorhost.app.ProgressPreloader"
                           >

Cheers,

Philip
