[PyQt] [SIP] Segfault with nested template types

[Casper Ti. Vector]

After lost of frustrations I seem to find the correct solution: use
> #define sipType_cell sipFindType("QPair<int, int>")
instead of
> #define sipType_cell sipFindType("cell")

Hope it helps anyone with similar problems in future.
