Add an example site

The theme shipped no runnable site and documented no configuration, so
every setting it reads had to be discovered by reading the templates,
and there was nothing to build against when changing them. The build
failure that unset RSS limits caused would have been caught immediately
by an example site.

The two configuration files are the separate website and capsule
configurations the readme asks for, annotated with what each setting
does and which are optional. The content demonstrates entries, tags,
references, a standalone page and the front matter keys that control
them.

Also ignore build output, which no rule previously covered.
