More author stuff:

Hey there,

that Authors-Dictionary-Idea set a spark in me and I made this following changes ontop., too. Making our blog a big more personal and also give credit to the authors:
 * The dictionary now also contains an about-section, giving some context to the author
 * the dictionary now also contains an image the author can link to
 * the author is named, shown (picture) and the about is shown under their blog-posts (see screenshot)
 * there is a /authors.html generated out of the config-section (see screenshot)
 * the authors.html is linked in the footer of each page
 * the author is propagated in the atom-feed

This looks like a bunch of changes but after the meta-tags have been merged, there are only two or three commits to look at.
