Use markdown sources

[memowe]

I wrote this as issue #8 before but maybe it's better to go one step back and use this platform to discuss a strategy before.

Thanks for all your effort in this important project!

I think it would be great to have the book‘s content as markdown files instead of HTML files:

Pros:

1. It would make contributions much easier as it wouldn‘t require web authoring skills.
2. It would make diffs much more readable.
3. With pandoc and custom templates it would make exporting HTML, PDF or EPUB a very transparent process.

Cons:

1. Lots of work. Especially when it‘s a requirement to produce (almost) the same HTML result as before.
2. ...?

What do you think about it?

I'm willing to help if the community thinks this would be the right thing to do. Im looking forward to ideas and opinions. :)
