[PyQt] [SIP] Proposed patch for isPyOwned function

[Alexis Boutillier]

Hi,

Here is a patch we made in sip to have a function letting us know if a 
sip wrapper is own by C++ or python from python.
This is only a call to the existing sip method sipIsPyOwned.

We use it to track wrapper that are owned by python whereas they should 
be owned by C++ for garbage collecting problems.

Regards,
