Add Journey Modal - Githubissues

@samepant I am almost wrapped up here, but a few things remaining:

We need to actually show this modal when it's supposed to. I am assuming this will be a localStorage thing, but for now I just have a hardcoded variable in index.tsx.
I need the URL for the final slide.
I need to test the other modals to make sure my changes didn't break them.

We could also potentially trigger the music (or maybe just the background track) on the first click here once we merge the music branch in.

Also, one more thing to note is that I had merged the responsive-ish branch in here in order to build off the proper sizings, so we'll probably want to merge that into master before this one.
