0029451: Information Message Alert to debug an algorithm or object functionality

Modifications: - Message_AlertExtended to store additional parameters (attributes, composite alert container, performance meter) - Message_Attribute and inherited classes to store custom information about alert - Message_CompositeAlerts to have hierarchical structure of alerts - Message_PerfMeter to automatically calculate time between alerts adding into report - Message_ReportCall back to be able to react to message report filling. - Import/Export message report report. Currently it is implemented using XmlDrivers_MessageReportStorage - MessageView/MessageModel - Inspector plugin for GUI presentation of Message_Report (cherry picked from commit e4529dcf83b12759e47efb89ded8207f802556a7) Conflicts: tools/ViewControl/FILES tools/ViewControl/ViewControl_PropertyView.cxx tools/ViewControl/ViewControl_PropertyView.hxx tools/ViewControl/ViewControl_Table.cxx tools/ViewControl/ViewControl_Table.hxx tools/ViewControl/ViewControl_TableModel.hxx tools/ViewControl/ViewControl_TableModelFilter.cxx tools/ViewControl/ViewControl_TableModelFilter.hxx tools/ViewControl/ViewControl_TableModelValues.hxx tools/ViewControl/ViewControl_TableProperty.cxx tools/ViewControl/ViewControl_TableProperty.hxx tools/ViewControl/ViewControl_Tools.cxx tools/ViewControl/ViewControl_Tools.hxx (cherry picked from commit 68876fcc5a) (cherry picked from commit 9a3d03bedb29dbf0124f5d53478d331d7ba877ff)
