* Moved FragmentController out of the FragmentControllerApplication

New stand-alone class FragmentController, to minimize dependency
between FragmentController implementation and the Application.
Also helps making the code more readable.

Note : application code imports need to be updated :

import
org.ymkm.lib.controller.FragmentControllerApplication.FragmentController;
=>
import org.ymkm.lib.controller.FragmentController;
