[Insight-developers] purify errors on VC++

[Lydia Ng]

4 of the leaks come from MemberCommand/SimpleMemberCommand:

They have there own implemenation of New().
It is almost identical to the one defined in itkNewMacro
except for the part which UnRegister the rawPtr.

I replaced New() by itkNewMacro - this fixes the leak.

Please let me know if this has other undesirable
effects.

----------------------------------------------------
One of the leak is from line 131 of the BasicArchitectureTest:
itk::OutputWindow::SetInstance(new TextOutput);

This has been fixed by using New instead of new.
-----------------------------------------------------

The UMR's are definitely a Microsoft problem!
I get them also with the following simple program:

template <class T>
class MyClass
{
 public:
  static Test()
  {
    std::cout << typeid(T).name() << std::endl;
    
  }
};

int main()
{
  MyClass<unsigned char>::Test();

  return 0;
}
