Close child windows and dialogs with main window

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.
