Activate new language-code: Aruban Papiamento [[[Portal:Pap-AW|pap-AW]]]

In the meantime, here's a direct link that should work as a start: https://translatewiki.net/wiki/Special:Translate?filter=%21translated&action=translate&language=pap-aw&group=core
This link is for core MediaWiki. You can select other components, such as "Visual Editor" in the project selector on the top right side of the screen.
