[PATCH 4/4] MainWindow: close all windows once we close the main one

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

This is useful if we have more non-modal windows and we want
them simply to close with the main one without explicitly
creating class member variables to point to such instances.

A practical example would be the debug window created in
ProfileWidget2() (diveDepthTableView) which holds
the depth profile values.
