[PyQt] Migrating the PyQt Wiki content

[David Boddie]

Following a recent discussion about this, I've obtained a dump of the Wiki
(thanks Torsten!) and have started to import the most useful pages into the
Python Wiki under the PyQt page/namespace:

  https://wiki.python.org/moin/PyQt

The pages I focused on importing are the ones that are indexed on the Sample
Code page:

  https://wiki.python.org/moin/PyQt/SampleCode

I find it useful to be able to add quick solutions and recipes to that page
for later reference. I'll be adding more pages to the Wiki as I discover
broken links.
