Message_Printer - define GetTraceLevel()/SetTraceLevel() methods in base interface. Implement message gravity filter in Draw_Printer. Add new Draw Harness command dtracelevel to show/change message gravity filter. Redirect default messenger to Draw_Printer within TKDraw instead of TKXSDRAW Draw::Commands() - assign Draw_Printer only once

-- The ostream may be either externally defined one (e.g. cout),
|
|
-- or file stream maintained internally (depending on constructor).
