Fix all missing copyright notices at once

There are a couple of places where the copyright notices are missing from the code. To prevent keeping this from returning in reviews I think we should automate this task to prevent this unnecessary overhead.

Could we use the year of first publication (a fixed year) because then we could automate this task? I would suggest 2014.

@thijskh what do you think about this? (bstrooband - Jul 19, 2019)

Fine to add to all files with a fixed copyright year (Thijs Kinkhorst - Jul 19, 2019)

But what about new files? They should reflect the year they are created right? It feels really counter-intuitive to set them with a year from the past.

Also, what should be the copyright year for the files currently not \'tagged\' with a copyright? The first Github tag of EB (1.0.0) is from march 2011. But development might have started at an earlier point in time? (Michiel Kodde - Aug 22, 2019)

The year really does not bear any significance and files are part of the total product.

Fine with me to put "2010" everywhere (year of first commit). Or the year the notice was added to the file (so a notice added today lists 2019). But please no updating of years after that. It serves no purpose and pollutes the git history. (Thijs Kinkhorst - Aug 23, 2019)

Updated the year to 2010 (bstrooband - Aug 27, 2019)
