[PyQt] More pythonic API

[Arve Knudsen]

My impression is that Phil intends for PyQt to generally resemble Qt as
closely as practically feasible. This approach has advantages. It implies
less complexity wrapping-wise, since the mapping is mostly direct, and once
you know Qt itself you can easily work with PyQt (principle of least
surprise). I find that PyQt being non-Pythonic mostly represents a
threshold, which has little practical bearing once you have some experience
with (Py)Qt. Also, it's a good thing when switching back and forth between
C++ and Python (which some of us do).
