A way to headless API usage

[sveetch]

Is your feature request related to a problem? Please describe.
Currently all serializers include objet detail URL so it involves url resolution on HTML frontend, therefor the HTML frontend is required.

Describe the solution you'd like

Serializer may be flexible enough to work without HTML frontend urls enabled, so Lotus could be a headless blog as a "API only" (but still need Django admin to write contents);

I've inspected the API in its current stage and it is almost ready since all the included links everywhere are always pointing to the API, there is still only the detail URL path (with hostname) but it won't involve any resolution and is only given as an alternative in addition of the detail API endpoint.

The only thing we could do here is to make the detail URL path optional so API payload would never include links to HTML views, only the API. So the other API issues may be a higher priority.
