Generating links with `link text <./path/to/doc#anchor>`__ does not work for html.
It produces a link to `./path/to/doc#anchor` instead of `./path/to/doc.html#anchor`.
It would be tempting to add `.html` before `#` but would likely cause some more issues
when generating the documentation as pdf or epub.
References on the other hand will work regardless of the output format.
Need to flip order of creating `BlogIndexRelatedLink` and `BlogIndexPage`, otherwise `BlogIndexRelatedLink` references `BlogIndexPage` before it's been created and you get:
```bash
ERRORS:
blog.BlogIndexRelatedLink.page: (fields.E300) Field defines a relation with model 'BlogIndexPage', which is either not installed, or is abstract.
```
While the project template is intended to be as generic as possible, and not everyone will want to use requirements.txt (some would prefer to use setup.py to define requirements, for example), we need some way to formally indicate that the project template is specific to Django 1.8.
