Proxy the resources through our server instead of always requesting
them from the CDN, leaking lots of usage data.
This prefetches the resources at server startup (instead of e.g.
adding them to the build environment statically), which is a nice
compromise I think. It will also keep the integrity verification in
place, but that is still done in the client.
Adds `rel=preload` as well, so we start fetching asap.
No caching (yet). We could easily add a hash over the content though
so the client never has to re-request the resources.
