Changed opensource to free and open source

In my opinion it is important to distinguish that we want to support
Free and Open Source software, and not only open source. The term
'open source' is often misused for software where one can look at the
source code under some NDA. Free Software makes sure, that the
specific software has a DFSG-compatible license.
Fixed indentation for second level list detailing harassment
Merge pull request #27 from stooj/67472afd013b14190aa06ea7d20dbeb9486eca35

Indentation fix and nothing but the indentation fix.
Merge pull request #26 from pettter/master

Some automation changes
Cleaned up and trimmed down some language
Removed package a4

The package a4.sty as well as other LaTeX packages should not be used
in current documents (according to l2tabu
<URL:http://mirrors.ibiblio.org/CTAN/info/l2tabu/english/l2tabuen.pdf>).
Merge pull request #32 from qbi/patch-3

Removed package a4

This should result in no large changes, as a4paper is already specified.
Using scrbook instead of book

I would suggest using the document class scrbook.
This is part of KOMAScript 
(<http://www.ctan.org/tex-archive/macros/latex/contrib/koma-script/scrguien.pdf/>)
and uses some reasonable default settings for documents. It uses A4 by
default, so the option is not needed anymore.
Added checks if directories exist
Merge pull request #33 from qbi/8cdaea6bac954708c465e4f4f6aef68ea89de0cc
