0032055: Draw Harness, ViewerTest - add more vmanipulator position adjusting options

Browse Source 
Draw::ParseOnOffIterator() - added auxiliary wrapper over Draw::ParseOnOff() for more compact syntax.
strncasecmp() definition for msvc compilers has been moved to Standard_CString for consistency with strcasecmp().
vmanipulator command has been refactored to use more straightforward parser.

vmanipulator now accepts "-adjustPosition {0|center|location|shapeLocation}" options
adjusting position to object's AABB center (existed before), object's local transformation or TopoDS_Shape location.
