[PyQt] pyqtdeploy, Windows and dynamically loading things

To continue my habit of answering my own questions...

Option 2) from below is the correct one and the reason _socket was 
failing to be imported was because I had neglected to pick up the 
necessary pyd files...

My application now compiles and just about limps along (*lots* of things 
I need to fix yet!).

Just want to add a huge thank you to Phil for all your tireless work on 
PyQt, sip, pyqtdeploy and all the other things you do.

Cheers, Rob
