* Moved the layer visibility and transparency, from instancerenderer.cpp to layercache.cpp and improved it. Note: Now you can set a instance completely opaque, when their layer is fully transparent or reverse. If both have a transparent value then the result from layer-instance is used.

<VBox opaque='1'>
	<Button name="moveButton" text="Move here" />
	<Button name="talkButton" text="Talk" />
	<Button name="kickButton" text="Kick" />
	<Button name="inspectButton" text="Inspect" />
</VBox>
