add the setup for basic html source decorator

@davidpett thanks for raising the PR!

How does this patch differs from the work done in #7. As I understand there are multiple preview setups within Storybook. #7 implements the JSX version and this one the html one. As I mentioned to @dogoku before, it would be nice if we could allow users to choose. I personally don't have a strong opinion here.

@christian-bromann right, this will have the basics and allow easy addition of more languages. I see it as something that @dogoku could build onto by just adding the jsx decorator

To be fair, I rushed into my PR not considering all the use cases, so I don't mind rebasing my work, given that this PR will fix an immediate problem and create the groundwork to support both language modes.

So you can go ahead with this PR and I will pick up my work over the weekend, as I don't have time to work on this during the week.

Thanks for your feedback @dogoku I will go ahead and review/merge this then.
