Fix: shortcode images don't load after build

Browse source 
This fixes an issue where images added with the [`image` shortcode](https://github.com/pawroman/zola-theme-terminimal#image) are visible via `zola serve` but not `zola build`.

It works by [prepending](https://tera.netlify.app/docs#concatenation) the site's base URL to external image URLs so `https://www.awesomesite.com/flower.png` is just as valid as `http://127.0.0.1:1111/flower.png`.

External images are differentiated from internal images by the presence of `http` at the beginning of their URL.

Fixes issue #36.
