Containerisation and Fuctionality Upgrade (#539)

* Disabled meta tag checking and stopped sphinx-build treating warnings as errors, due to replacing absolute links with realtive links (which sphinx doesn't like)

* Disabled tests.sh due to failures caused by older documentation not having meta tags.
