Add markdownlint to Travis CI

Description

We should add a markdown linter with the corresponding rules to Travis CI to enforce standards and consistency for Markdown files to help with reading and writing files with markdown markup. It comes with 45 pre-packaged rules, which can be adjusted to fit your needs. E.g line-length, no-bare-urls or no-empty-links.

In the beginning a small defined set of rules should be applied which can later be extended as markdown markup quality improves.
