author name parsing #220

When parsing author names a file name_particles.txt is used to identify particles like van, der, Dr., Mr. etc.. and get rid of them when identifying the name and the surname. This file I suspect it was left behind in some refactoring and in fact, was not being used. This PR moves it again in the proper classpath location and introduces few non functional improvements in its implementation.

Via the helpdesk (ticket #181), a user confirmed that the names with particles (which she calls "insertions") are:

<Name> van <Surname>
<Surname>, <Name> van
Van <Surname>

And that this applies not only to Dutch names but also to names of other countries (e.g. von)

We thought we solve the problem, but the user reported again some problems with her names in some cases.
She did a search by ORCID id and sometimes her name is still wrong:
