removed CrossAppUI from system-ext

It caused some errors which prevented loading of enyo.js on OWO. Did not
find out how to easily fix it and I'm not using it anyway.
removed cordova

I'm not really using cordova currently... everything I need is in webos-
lib apart from the stageReady() call.
fixed scrolling of change list.
added output for call to applicationManager

Somewhow running the app does not work anymore on
newest (2013-10-21) emulator image.

Added issue for that.
removed unnecessary package-info files
renamed service, affects some config files, too.
Move sysbus configuration into service subdirectory

Belongs only to the service so keep it there instead within the top directory.
