[Feature] Add previews for bones in bone fields

[ViTeXFTW]

Problem

When writing fields which references models and model bones, it is difficult to see if the bone specified in the value is correct.

Proposal

For fields which references bones it could be nice that the bone got rendered and displayed similar to the model previewing.

Examples

    RemoveModule ModuleTag_01

    AddModule
        Draw = W3DTruckDraw Moduletag_01New
            DefaultConditionState
                Model = NVSupplyTk
                HideSubObject = CARGO ; -> SHOW PREVIEW WHEN WRITING HERE
            End
        End
    End
End
