Error 500 internal server error when trying to print data table

[jonrandahl]

This PR resolves the error reported in ticket #396 by updating the print presenter to use .try(:first) which resolves by returning nil without failing if the requested element does not have the method .first, i.e. is empty or nil

Additional Changes:

• Updated the print template to include the Google Analytics tracking script for the print page as well as importing shared header content for unification of presentation
• Minor tweaks to the Makefile to remove duplicate variables (SHORTNAME) as well as introducing new targets for check and local for streamlined development tasks, alongside removing incorrect and erroneous commands where applicable
• Reorganised .gitignore file to improve readability as well as added comments to group and explain rule application
• Removed duplicated rubocop command
• Reorganised gemfile to create test specific group and lock gem versions to current version of Ruby in use
• Minor Rubocop fixes including preventing rubocop from parsing the bin/s-query file which is used to resolve the fallback location for the Apache Jena Fuseki s-query file added in this commit
