[PyQt] need help with sizing QStackedWidgets

[Eric Frederich]

Replying to self with a solution in case someone else comes across this
problem.
david_boddie on freenode's #pyqt channel helped me out.

A solution was to call....
    layout.setRowStretch(len(labels), 1)
... after adding the spacer.

Another solution was to nest the grid layout into a BoxLayout and call
addStretch.
