[texworks] compilation of TWPythonPlugin.cpp failed

[Jonathan Kew]

I think this is an issue with the version of Python. We need an #if... in the source that checks the version of the Python headers, to choose the right type for that variable, but I'm not sure exactly what version number to test.

If someone could check the declaration of PyDict_Next() through various releases of Python 2.x, it should be easy enough to figure out what's needed. Or perhaps it's even mentioned in release notes or changelog somewhere.
