"More" button with excerpt separator in Jekyll Theme

[ChristopherA]

As per #4:

Our blog page currently shows each post up to the excerpt separator, which is what we want. However, it should also include a “more” or “read the full article” or something down at the bottom for any article whose view on this page is terminated by an excerpt separator

This is now possible, we just need to remember to add:

<div class="bold--excerpt--node">Read More</div>
