Populate default values before echoing help text

Browse Source 
Testing showed that it may take a few seconds for the default values to
populate.  If the help text is shown, “Enter the public IP address…,”
but no prompt is shown, the user may get confused and try to enter the
IP address before mailinabox has had a chance to figure out and display
a suitable default value.
