nds 6822a3bef1 0029674: Improvements in Inspector tool 
- preferences for dock windows geometry, tree view columns and current view projection;
- ViewControl package for common functionality between plugins;
- processing Location and Orientation for external TopoDS_Shape object
- 'F5' key to update content of each plugin
- visibility column in tree view (used now only in ShapeView)
- properties child item for context (presents tree of current Filters of context)
