Fix for #348 - migrate our NextJS project to a pure webpack project w/ a single bundle
- [x] Switch from `next/link` to `react-router-dom`'s link
> This part was easy - just change the import to `import { Link } from "react-router-dom"` and `<Link href={...} />` to `<Link to={...} />`
- [x] Switch from `next/router` to `react-router-dom`'s paradigms (`useNavigation`, `useLocation`, and `useParams`)
> `router.push` can be converted to `navigate(...)` (provided by the `useNavigate` hook)
> `router.replace` can be converted `navigate(..., {replace: true})`
> Query parameters (`const { query } = useRouter`) can be converted to `const query = useParams()`)
- [x] Implement client-side routing with `react-router-dom`
> Parameterized routes in NextJS like `projects/[organization]/[project]` would look like:
> ```
> <Route path="projects">
> <Route path=":organization/:project">
> <Route index element={<ProjectPage />} />
> </Route>
> </Route>
> ```
I've hooked up a `build:analyze` command that spins up a server to show the bundle size:

The bundle looks OK, but there are some opportunities for improvement - the heavy-weight dependencies, like React, ReactDOM, Material-UI, and lodash could be brought in via a CDN: https://stackoverflow.com/questions/50645796/how-to-import-reactjs-material-ui-using-a-cdn-through-webpacks-externals
