Replace remaining usages of Gtk.MessageDialog
There are some remaining places where Gtk.MessageDialog is being used (besides the ones using the old Utils.showDialog() that has been replaced with toasts.
-
ExportViewDialog, this could use an Adw.Toast -
MapView, there is a dialog used for confirmation on loading large shape layers, replace with Adw.MessageDialog probably -
OSMEditDialog, shows an error message when failing to load OSM data, and on upload failure. This could be a toast shown in the main window (as the dialog is closed on these errors) -
PrintOperation, shows a dialog to abort the ongoing print operation. This should probably be an Adw.MessageDialog
