[PATCH 1/3] Close child windows and dialogs with main window

[Lubomir I. Ivanov]

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

Most child windows should be closed with the main application
window otherwise if left open and if making specific
modifictions could potentially cause a SIGSEGV.

To solve that we mark all custom windows/dialogs with
the Qt::WA_QuitOnClose attribute on instance creation.

resent due to conflicts in master.
