Rotate with degrees

Now you can rotate with degrees. 

code:

		final EllipticalOrbitAnimation3D anim = new EllipticalOrbitAnimation3D(
				mCenterPoint, 
				getCurrentCamera().getPosition(),
				0, 60);
		anim.setTransformable3D(getCurrentCamera());
		anim.setDuration(8000);
		anim.setInterpolator(new DecelerateInterpolator());
 
      registerAnimation(anim);
        anim.play();
Updated parsers to support File as a parameter. This is necessary to support the Rajawali Serializer tool and allows for use of the assets folder should someone want to use that instead of resources or sdcard location.

EllipticalOrbitAnimation3D  rotate with degrees
Modified #704 EllipticalOrbitAnimation3D.

Changed angle from int to double to allow for arbitrary degree rotation. This is particularly important if the periapsis is large or the eccentricity is near 1. Also cleaned up some formatting issues.
