Add support for importing software related biblatex entries

[rdicosmo]

biblatex-software is a biblatex package now part of CTAN and TeXLive. It addresses the needs for citing software in biblatex, by adding the relevant fields for software that are missing in the stock biblatex, and provides 4 different entries @software, @softwareversion, @softwaremodule and @codefragment, to enable citation of a software project (e.g. Scikig-Learn), a version (e.g. OCaml 4.09), a module in a modular software project (e.g. Voronoi diagrams 1.0 in CGal 3.02), or a code fragment (e.g.: the core mapreduce algorithm in Parmap 1.0).

It would be great if JabRef could import and manage these entries, that are now being progressively adopted in journals and open access repositories.

[The documentation is available online](https://ctan.crest.fr/tex-archive/macros/latex/contrib/biblatex-contrib/biblatex-software/software-biblatex.pdf, but feel free to contact me for any question you may have about it.

Thanks for the suggestion, however, this is already implemented since JabRef Version 5.1

If your library is in biblatex mode, you can see them in the new entry dialog:
