The structure of InspectorWidget::m_groups changed, so I had to update my new code accordingly.
Updated the InspectorWidget::m_groups code a bit to be more readable.
Discovered the initial property group visiblity state wasn't being set correctly when a material was first opened, so groups weren't initially hidden when they should have been. This had to be fixed in different ways for MaterialEditor's inspector and MaterialComponent's inspector.
