By default when using fade labels they always fade in even when the designer only want to use a fade label for scrolling or fading it out if it's too long.

All controls used in guilib set this property to false. It is only set to true for fade labels on their own.

This should be made a property so that skinners can use fade labels without the fade-in effect.

The property should default to "true" to keep backwards conpatibility with the current skin engine behaviour even if "false" would be more suitable.
