The well commented conf/app.ini file that comes with the code shows the
ROOT_URL (i.e. setting.AppURL) as:
ROOT_URL = %(PROTOCOL)s://%(DOMAIN)s:%(HTTP_PORT)s/
However the installed custom/conf/app.ini file does not include this setting as
shown, and the default in the setting module was hard coded to
http://localhost:3000/ instead of what is shown above.
With this change the ROOT_URL will default to what is shown above if it is not
set in the custom/conf/app.ini.
Of course it is still possible to override the default by adding the ROOT_URL
setting to your custom/conf/app.ini file as usual.
