Published a new landing page

Another week, another new landing page! This is a more cosmetic update, after adding the additional content last update the layout wasn't quite working as well, so a rejig was needed.

I also wanted to add an image or two to the homepage to make sure people who aren't familiar with a no spend month have a bit more context, as they say a picture paints a thousand words.

Right now it's just a single image (well two, but very similar, one for mobile and one for desktop/tablet) but as I add some of the features I mentioned previously I can add screenshots to give examples of those.

Other work done includes a refactor and then subsequent bug fix to the email verification workflow and being more active on Twitter with little updates.
