The template delete dialog was coded in such a way that the default behavior
was to delete the template/folder unless the user pressed no. This
caused the template to be deleted if the dialog was closed using the "x"
button. I changed the logic so that the dialog will only delete the
template if the user presses yes. Any other button press will do nothing
but close the dialog.
