Feature: first draft to display meta data

[googol42]

• Add support for meta data.

The html is not perfect. But IMO for the Prozessanalyse sufficient.

The syntax includes everything which was required/discussed on 27th March (sources, author name, author url, reviewers' names/company/..., link to reviewers' webpage, reviewed commits). Security Features can be realized by using tags.

Syntax for md files, here as part of java_easy_AES_string_encryption.md:

Yields this page:

Nice, I have only a few remarks:

• Move everything below the example, so the example stays the first thing to bee seen.
• Don't use h2, but a less big heading.
• I'd expect the source code under the heading "sources" not the references
• I'd expect "Version History" instead of "changes to this example"
• I'd expect reviews to be a separate heading.

@kmindi As discussed. The jekyll-last-modified-at plugin is not available on github page (github/pages-gem#119) So, one have to enter the date oneself. However, I copy this value to site.last_updated which then displays the date in the footer.

Note, the spelling mistake in the screenshot was fixed (Reviewes). If you like to have other names for the headings, feel free to change them on this branch.
