0023442: Provide the access to the functionality of Geom2dHatch_Hacher via IntTools_Context

Browse Source 
class IntTools_Context
- the method:
Geom2dHatch_Hatcher& IntTools_Context::Hatcher(const TopoDS_Face& aF)
has been added.
The method returns the reference to 2D hatcher for given face <aF>

class IntTools_Context
- the method: IntTools_Context::~IntTools_Context()
has been modified in terms of I.1.
