added "float approxLength(int samples)" to Path interface and added implementation within existing Spline-classes
Less GC in RoboVM iOS backend. Will now use a single UITouch and a single UIAcceleration instead of creating new ones on each touch/acceleration event.
extracted local variables to avoid allocation on each call
removed unused tmp2
fixed formatting and adapted PathTest as suggested by @Xoppa
Added I18N support
Added a simple I18N test.
These AsynchronousAssetLoaders now release their assets when finished.
Cleaned up MathUtils and added lerp method.
Button stays "pressed" when clicked "rapidly" in non-continuous rendering mode...
Calling Gdx.graphics.requestRendering() in a ClickListener doesn't solve the problem.
One might change the `visualPressedDuration` like this :

```
// hach for releasing the click in non continous rendering
ClickListener.visualPressedDuration = 0f;
```

but it's pain in the ass when switching from continuous to non continous rendering.
