New rendering of the file architecture plot

Until now the file architecture plot at the directories ontop of the
top-level files. This made it hard to visually identify the top-level
files. They are not placed ontop of the sub-directories and some space is
added to highlight the files in the top-level directory and those in the
subdirectories.

Two other changes were made:

 - The symbolic links created in the top source directory are also shown.

 - The coding of this figure was made much more elegant by defining a
   PGFPlots node class and just changing the things that are direrent
   between each directory.
