Export Zotero items keys with BetterBibTeX

It is possible to export Zotero items keys while using BetterBibTeX with this little postscript:

if (Translator.BetterBibLaTeX || Translator.BetterBibTeX || Translator.BetterTeX) {
    reference.add({ name: 'key', value: item.itemKey});
}

So the .bib will contain key = ITEMKEY so we can reconstruct a Zotero URI: zotero://select/library/items/ITEMKEY
