Bug in shared_ptr.i

Hello!

I have found a bug in shared_ptr.i, I think :P

In the toplevel user macro SWIG_SHARED_PTR_DERIVED it should not refer to

   SWIG_SHARED_PTR_NAMESPACE::shared_ptr

but rather

   SWIG_SHARED_PTR_QNAMESPACE::shared_ptr

I found this while trying to use boost_shared_ptr.i for wrapping std::tr1, 
which is explicitly said to be supported in the same file. It took me some 
time to figure out that you couldn't just use:

   #define SWIG_SHARED_PTR_NAMESPACE std::tr1

but that you have to use 

   #define SWIG_SHARED_PTR_NAMESPACE std
   #define SWIG_SHARED_PTR_SUBNAMESPACE tr1

and then it took some more hours to figure out the bug I am reporting.

Thanks for a great program!

p.s. a diff is attached showing the change to 'shared_ptr.i'
