Grouping of DI controller context menu

Right-click a layer in the Scene Graph and select Set datainput controller to bring up the context menu.

The grouping of the objects in the menu seems a little bit off, i.e. there are AO items in three different groups and IBL items in two different groups. This issue seems to be more or less valid for all objects, i.e. layers, camera, lights, 3d objects.

Additionally "Set datainput controller" should be "Set data input controller".
