Until now the software configuration parameters were defined under the
`reproduce/software/config/installation/' directory. This was because the
configuration parameters of analysis software (for example Gnuastro's
configurations) were placed under there too. But this was terribly
confusing, because the run-time options of programs falls under the
"analysis" phase of the project.

With this commit, the Gnuastro configuration files have been moved under
the new `reproduce/analysis/config/gnuastro' directory and the software
configuration files are directly under `reproduce/software/config'. A clean
build was done with this change and it didn't crash, but it may cause
crashes in derived projects, so after merging with Maneage, please
re-configure your project to see if anything has been missed. Please let us
know if there is a problem.

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

With this commit, the copyright information of some files have been
modify in order to include the work of Raul Infante-Sainz.

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).
