create landing page for all the stories

ref #23 A new landing page, displaying a grid of all geostories, has been created

@DavidQuartz do we really need those less files? Isn't the style already available?

@giohappy the less files are only used in development, from which the css styles are compiled. This is the current work flow. Even though the less isn't need in production, it is important to have there so that the styles don't get overridden by a future commit following the same work flow.

@DavidQuartz I didn't notice that all the styling inside the less file is only related to the custom grid on the homepage. That's fine

[DavidQuartz]

Ah yes they only relate to the custom grid @giohappy
