base_url should include port?

[czarop]

In the code around generating a subscription confirmation link for the email, the link address is stated as being '{base_url}/subscriptions/confimation...' (base_url being taken from base.yaml for the local version of the app).
In base.yaml, base_url is "http://127.0.0.1" - I believe this should be 'http://127.0.0.1:8000' , otherwise the confirmation link generated does not work locally.
