[PyQt] Updated PyQt Release Plans

[Phil Thompson]

As Qt v4.4 has been released a little earlier than I was expecting I'm 
dropping plans for a PyQt v4.3.4 release.

The current snapshot has been updated for the final Qt v4.4. I need to finish 
the new support for QMetaObject.invokeMethod() and expect to release PyQt 
v4.4 in a week or two.

Now would be a good time to check for any regressions...

...and now would be a good time to let me know of anything else that should go 
into the release.
