Ressource from URL

Features
#1

It would be nice for jabref to do some parsing of a website for @online ressources like
https://github.com/JonasMoennig/currentPageToBibTeX does

we could try to extract author etc from pages like stackexchange

#2

This is already partly possible with the JabFox addon: https://github.com/JabRef/JabFox

#3

sadly my OS is supported by Jabref, but not by Jabfox

#4

Support is planned, but we need help with it, it’s a bit complicated

#5
