Until now the shell scripts in the software building phase were in the
`reproduce/software/bash' directory. But given our recent change to a
POSIX-only start, the `configure.sh' shell script (which is the main
component of this directory) is no longer written with Bash.

With this commit, to fix that problem, that directory's name has been
changed to `reproduce/software/shell'.

Now that its 2020, its necessary to include this year in the copyright
statements.

It was some time since these three software were not updated! With this
commit the template now uses the most recent stable release of these
packages.

Also, the hosting server for ImageMagick was moved to my own webpage
because unfortunately ImageMagick removes its tarballs from its own
version.

Until now, the software building and analysis steps of the pipeline were
intertwined. However, these steps (of how to build a software, and how to
use it) are logically completely independent.

Therefore with this commit, the pipeline now has a new architecture
(particularly in the `reproduce' directory) to emphasize this distinction:
The `reproduce' directory now has the two `software' and `analysis'
subdirectories and the respective parts of the previous architecture have
been broken up between these two based on their function. There is also no
more `src' directory. The `config' directory for software and analysis is
now mixed with the language-specific directories.

Also, some of the software versions were also updated after some checks
with their webpages.

This new architecture will allow much more focused work on each part of the
pipeline (to install the software and to run them for an analysis).
