[PyKDE] SIP Changes to Support ActiveX

The current SIP v4 snapshot has a new implementation of connections between Qt
signals and Python slots/callables. This is needed to support "external"
signals from ActiveX controls on Windows. It may also be needed for DBUS
support in Qt v4.
Signal arguments that have an unsupported type are replaced with the
NotImplemented object. At the moment enums and mapped types are unsupported,
but this will be fixed in later snapshots. The same mechanism will also be
used to fix the PyKDE problem when typedefs have been used in signal
The way this has been implemented only works with Qt v3. Consequently, if you
are (still) using Qt v1 or v2 you must use SIP v3.
You will need to re-build PyQt. First you will need to hack PyQt's
configure.py so that the qtaxcontainer module gets built. Find the test for
SIP v4.2 and remove it...

The current PyQt snapshot includes a port to Python of the Qt webbrowser
example which embeds Internet Explorer in a Qt widget.
The qtaxcontainer module implements the QAxObject and QAxWidget classes - look
at the qaxobject.sip and qaxwidget.sip files to see exactly what has been
implemented. I would like feedback on this - is what has been implemented
useful? Does more need to be implemented for real-world applications?
