Add blog post on changes of our .bib serialization

[koppor]

This blog post reviews the history of JabRef 2.0 to now (JabRef 5.0) writing the bibtex file.

• What is currently missing is the layout of multiline fields. Maybe, this is not that important...

The rendered version can be easily browsed at
https://github.com/JabRef/blog.jabref.org/blob/add-bibtex-file-changes-over-time/_posts/2020-08-20-bibtex-file-changes-over-time.md.

Just found following in the comments

    /**
     * Get display version of an entry field.
     * <p>
     * BibTeX is case-insensitive therefore there is no difference between: howpublished, HOWPUBLISHED, HowPublished, etc.
     * <p>
     * There was a long discussion about how JabRef should write the fields. See https://github.com/JabRef/jabref/issues/116
     * <p>
     * The team decided to do the biblatex way and use lower case for the field names.
     *
     * @param field The name of the field.
     * @return The display version of the field name.

• Information about group serialization should also be included here (refs No user info about changing bib-format in 4.0 jabref#3251).
• While working on it, it should be checked if JabRef issues a warning about changing the semantic content of the bib file without any notice. If not, think about implementing it
• Check if the blog post contains words about that we keep "old serialization" if the entry did not change

Refs JabRef/user-documentation#227

• Include screenshots of settings dialog. See An option for not aligning = when JabRef saves/imports bib files as well as adds new entries jabref#8676.
