0030507: Visualization - introduce AIS_ViewController
ViewerTest_EventManager now inherits AIS_ViewController. Platform-dependent user input handling within ViewerTest has been revised to process events in common way through AIS_ViewController. The mouse navigation has been changed, so that left mouse clicked without modifers now rotates View. The rubber-band selection can be activated via Alt+LeftMouseButton. Selection is now done on mouse unclick and keyboard short-cuts take effect on unclick. Aspect_Window::SetTitle() - added new method configuring Window title. Introduced new types Aspect_Touch, Aspect_VKey, Aspect_ScrollDelta for processing window events in platform-independent way.
