Android Activity Launching (jogl.test)

Launching activity is in: jogl.android-launcher.apk
and directly derives from NewtLauncherActivity.
It daisy chains apk's via ClassLoaderUtil:
  - gluegen-rt.apk
  - jogl.all-android.apk
  - jogl.test.apk (*)

(*) This has to made configurable so the generic NewtLauncherActivity
    can be reused by any user application.

After preparing the ClassLoader (see above),
NewtLauncherActivity instanciates the configurable
user Activity and passes all it's activity calls down to it.
