[PyQt] ANN: PyQt v5.13.1, PyQtWebEngine v5.13.1, SIP v4.19.19 Released

[Phil Thompson]

PyQt v5.13.1, PyQtWebEngine v5.13.1 and SIP v4.19.19 have been released. 
These are all minor functional releases.

The wheels for PyQt3D, PyQtChart, PyQtDataVisualization and 
PyQtPurchasing have been updated with Qt v5.13.1.

This version of PyQt implements an alternative strategy for tidying up 
objects when an application exits. By default the new strategy is 
disabled. To enable it add the following to your script...

     from PyQt5.QtCore import pyqt5_enable_new_onexit_scheme

     pyqt5_enable_new_onexit_scheme(True)

The intention is to make the new scheme the default (and to remove the 
above function) in PyQt v5.14. I would really appreciate it if people 
could try out the new scheme (if only for 5 minutes) and let me know if 
it causes any problems. I'm hoping that 99% won't notice any difference 
and the remaining 1% will see an improvement.
