Portable Julia

Hi Stefan, I have plans to integrate Juliaup (GitHub - JuliaLang/juliaup: Julia installer and version multiplexer) into this distribution in order to update Julia from the command line. Juliaup in itself is a really cool project and might fill some of the gaps that Juliawin set out to fill (like easily having separate Julia versions on the same machine). Juliaup isn’t portable though in the same way as Juliawin, but Juliaup does make it easy to replicate an environment elsewhere, which might be better for most modern use cases. As you can tell I’m a big fan of Juliaup
