Figure out distribution mechanism(s)

Currently, the `dist/` folder is ignored from git. I'm generally of the opinion that this is a good thing, as that is a build artifact, and those should not go into version control. As pointed out here: https://github.com/Facet-MUD-Project/facetjs/pull/1#discussion_r432656112 we will need to do something more for our distribution.

I'm not really sure what the end goal looks like. Perhaps our end-user distributable is just a zipped up `dist/` folder? Do we deliver this to `npm`? I'm not really sure what the best path is here.

That said, this is far from high priority.
