Large refactorings in DataContainerInspectorWidget and DataContainerInspectorCanvas: 

* DataContainerInspectorCanvas uses the GeometryRenderer processor to render geometry
* DataContainerInspectorCanvas::_textures now uses DataHandle to improve thread safety avoid segfaults
* replaced some function calls with Qt signals to loose coupling
* removed obsolete fields and methods
