[PyQt] PyQt5-tools wheel for 5.7 (just designer for now)

[Kyle Altendorf]

I took Phil's cue and started a basic wheel with Designer and the PyQt5 
plugin.

https://github.com/altendky/pyqt5-tools/releases/tag/v5.7.dev1

But, while the pyqt5.dll plugin does load, my widgets don't load.  They 
do work with Windows and Linux 5.5.1 setups as well as Linux 5.7.  Last 
I checked, there wasn't really any diagnostic ability for this in 
Windows.  Has anything changed on that front or do I need to start 
adding debugging to the source code?

If people like this, I can start adding some other tools once I get 
Designer working for myself.  And get it on PyPi...

Cheers,
