Landing page

The very basic thing we need to do to switch from using the Tito (our ticketing platform) landing page is to have the following:

• home page that says basic info - dates, venue etc (just hardcoded text)
• embedded "interested people" widget where people can enter email - see https://ti.to/docs/api/widget#register-interest-widget
• we will use Goosetopher1 for now -> Goosetopher2 will be late November

Also want to integrate Smoke Signal here, I'll file a separate issue about that.
