AboutSystem: Hide border when "Show replicants" is turned off

Browse Source 
Create SysInfoDragger class and override its MessageReceived() method
to redraw the target view when draggers are shown or hidden.

Check that fDragger->AreDraggersDrawn() is turned on before drawing
the border in the SysInfoView::Draw() method.
