FXGLDefaultMenu layout is not responsive

[AlmasB]

module: fxgl
package: com.almasb.fxgl.app.scene
file: FXGLDefaultMenu.kt

FXGL/fxgl/src/main/kotlin/com/almasb/fxgl/app/scene/FXGLDefaultMenu.kt

Lines 90 to 92 in 43a1a24

	val menuX = 50.0
	val menuY = appHeight / 2.0 - menu.layoutHeight / 2

These are hardcoded, instead we should listen for (bind to) settings.prefWidth/Height properties.

You can check the result of this working (or not working) in fxgl-samples module by running a MenuSample and adding settings.setManualResizeEnabled(true);, then resizing the game at runtime.

Currently on resize, the hardcoded values will not result in a responsive layout.
