Verification activated, README added, Proper metadata in plot data

All the steps following the to-be-added (in 'README-hacking.md')
publication checklist prior to the final check from new clone have been
added:

 - 'README.md' file has been set.
 - "Reproducible supplement" was added just above the keywords, pointing to
   Zenodo.
 - A link to the to-be-uploaded data underlying the plot was added in the
   caption of the tools-per-year plot.
 - A new meta-data configuration file was added to store basic project
   metadata to be used throughout the project. This will later be taken
   into Maneage. For examle the project title is now stored here and
   written into the paper's LaTeX source and output datasets automatically.
 - Verification was activated and plot's data and LaTeX macro files are now
   automatically verified.
 - A complete metadata was added for the data underlying the plot.
 - A generic function was added in 'initialize.mk' that will automatically
   write project info and copyright in all plain-text outputs.
