[vtkusers] 5.0.2 Compile against Python 2.5

[David Car]

When compiling 5.0.2 against Python 2.5 on Linux I had to change line 771 in 
Common/vtkPythonUtil.cxx to a const char* to get it to compile.  It compiled 
fine against Python 2.4 without this error, so my guess is a bug fix or 
change in Python 2.5.  The diff is below:

771c771
<     const char *doc = t->tp_doc;
---
>     char *doc = t->tp_doc;

I haven't had time to verify a change in Python.  Anybody else experience 
this?
