Paul Fitzpatrick	bd6a54e901	(core) mitigate csrf by requiring custom header for unsafe methods ... Summary: For methods other than `GET`, `HEAD`, and `OPTIONS`, allow cookie-based authentication only if a certain custom header is present. Specifically, we check that `X-Requested-With` is set to `XMLHttpRequest`. This is somewhat arbitrary, but allows us to use https://expressjs.com/en/api.html#req.xhr. A request send from a browser that sets a custom header will prompt a preflight check, giving us a chance to check if the origin is trusted. This diff deals with getting the header in place. There will be more work to do after this: * Make sure that all important endpoints are checking origin. Skimming code, /api endpoint check origin, and some but not all others. * Add tests spot-testing origin checks. * Check on cases that authenticate differently. - Check the websocket endpoint - it can be connected to from an arbitrary site; there is per-doc access control but probably better to lock it down more. - There may be old endpoints that authenticate based on knowledge of a client id rather than cookies.

Paul Fitzpatrick	b71f2f2a10	(core) add a deployment test for Import-from-URL, and fix underlying issue ... Summary: * Adds a simple deployment test for the "Import from URL" button. * Makes server aware of plugin hostnames in the appropriate places. * Unrelated but convenient: allows following redirection when importing. Test Plan: Added tests. The `local_deployment` test works. A modified version of this works against `staging_deployment` (using a test url that doesn't require redirection; also staging currently has a hot fix that can hopefully be removed once the code fix included here is in).

Paul Fitzpatrick	5ef889addd	(core) move home server into core ... Summary: This moves enough server material into core to run a home server. The data engine is not yet incorporated (though in manual testing it works when ported).
