Resurrect installer.

Running `./bin/rails generate mailbox application --no-test-framework` generates:

```

class ApplicationMailbox < ApplicationMailbox
  def process
  end
end
```

which is not correct for the application mailbox. It shouldn't
respond to process but it should contain a routing hint.

Generally generators aren't meant to be used like the previous commit.
The mailbox generator can certainly add in the ApplicationMailbox
if missing, but it shouldn't be called with "application" as an argument.

Also adds back auto inserting an `ingress` config line in
`config/environmnets/production.rb`.

Fixes #13.
