Update gh-pages

[njbmartin]

There are a number of things we can do to make the homepage (gh-pages) much more user friendly, so then we can direct people to the website instead of the github repo and make more use of the site.

• Display version number. (Updated via CI)
• Display links to NuGet site and releases.
• Link to Docs.
• Basic usage sample / link to Getting Started guide in wiki.
• Links to Apps/Games using the library.

Please share your ideas and we'll add to this list.

Very good points. The second one doesn't require CI, as both NuGet and GitHub have links that direct you to the latest release.

The news section should also update at least when we do new releases. I think we're all rather busy with work/education though so it hasn't gotten a lot of attention.
