0026272: Visualization - provide a possibility to activate selection modes without opening local context

- picked or selected objects are now highlighted via owners instead of interactive objects;
- support methods for owners were added to AIS_InteractiveContext;
- dynamically highlighted owners are now displayed in immediate mode;
- selection without opening of local context is enabled by default;
- added "-local" key to vselmode command to enable selection in local context;
- selection filters are now completely supported in AIS_InteractiveContext;
- the idea of differencing of selected items onto current (in interactive context) and selected (local selection) was eliminated;
- all calls to "current" were replaced by calls to "selected" in terms of future local context removal;
- AIS_InteractiveObject::mySelectionMode was removed;
- now each selectable object can define own selection mode for "global" selection of the whole object;
- whole object selection mode is 0 by default for all standard interactive objects;
- immediate structures are now added to topmost and top layer lists;
- added support of drawing immediate structures in different layers;
- unused code for immediate mode was removed;
- vfeedback and vexport commands now produce correct output for raytrace mode.
