Fading of propertyowners through GUI, and more owners with fade property (#2557)

Browse Source 
* Add property in OpenSpaceEngine for fading duration when enabling / disabling

* Add interface for fadeable components and apply to renderable

* Make layers a fadeable component

* Make globelabels a fadeable component

* Make labelscomponent a fadeable, and give it an enabled property

* Make screenspace renderables fadeable components

* Introduce concept of parent fadeables, to fade out subowners with parent

* Make rings fadeable as well
