Installable PWA is online

Even though I haven't had a chance to work on Veghacker since December, I have still been using it every day, so that's a good sign.

I had a bit of time off from my day job this week, so I created a logo and sorted out the basics of making Veghacker a PWA that can be installed on your phone's home screen.

This is not even an MVP yet, but it's usable.
