Add CORS access-control-allow-origin to allow connections from other web apps like "letterbox"

[johanbove]

When connecting a replica-server-glitch to an instance of "letterbox", for instance on https://tools.earthstar-project.org/, the browser will refuse to connect to the remote Glitch server as it is missing the "“Access-Control-Allow-Origin" header with value "*" to allow incoming connections from any other domain.

Could it be made an option in the Glitch project to set the allowed domains?

Oh duh, that's what I get for only testing with the CLI. I think this should probably be the default rather than an option.

Added to the replica-server lib, and have updated this repo and the Glitch project. Thanks for catching this!

You're welcome :-)
