[PyQt] SIP template-based class with argument having default constructor as default value

[Shaheed Haque]

Thanks for the replies. To summarise:

1. The "::T has not been defined" should be fixed in a snapshot RSN.
2. There is a workaround for the templated superclass (Denis, thanks
for confirming it works). Do you think it might be addressed in a
subsequent release? I ask because there is plenty of other stuff for
me to get on with that if I can defer writing all the custom logic
this would need, I'll likely just be patient.

Now, speaking of getting on with things, I found two other things that
SIP does not like, but I guess it would be better to start different
threads for those. Phil, do let me know if you prefer me to send
reports in some way other than the mailing list.
