Per Repo server-react-render and main.js

[ddfridley]

If a repo like undebate-ssp is including the undebate and the civil-server, pages that get rendered by the complete build import one main.js file that has all the logic for everything. But if a user visits a page that's just part of undebate then the main.js contains more than is necessary.

For example if one goes to cc.enciv.org/undebates they get the top level page for undebate-ssp. But if one visits https://cc.enciv.org/san-francisco-district-attorney they get a page from the undebate repo - but it's rendered by App from undebate-ssp and both have a common main.js

When a projects server starts - in app/start.js there is the code

import App from './components/app'
   ...
   server.App=App

This is where the App from the repo of the top level project is being set.

In addition, all pages of the different repos/projects are rendered with on common app/components/app.js wrapper and use the same
app/server/routes/server-react-render - though maybe this is okay and we need to just factor our what needs to be project/repo specific, it's possible that this should be per project rather than the same for all cases.
