- Making RoboContext generic so it can take the type of application a context is related to.
- Removing configurationLocation() from RoboContext and making it only required on RoboApplication. RoboContext now needs to retrieve the Application instance it's tied to via <A> getApplicationContext().
- Changing DroidGuice.instance() references by RoboGuice.<DroidGuice>.instance() to avoid warnings
- Making roboguice warningless!
