Mount folders as endpoints

As of v0.9.9, NodeCG supports a nodecg.mount array in your bundle's package.json. These mount declarations are simple objects with two keys: directory and endpoint.

directory is a relative path from the root of your bundle which tells NodeCG which folder you'd like to mount as a custom endpoint.

endpoint is a URL relative to http://localhost:9090/bundles/${bundle.name}/ which tells NodeCG what URL you'd like to serve your directory from (Of course, substitute localhost and 9090 with whatever host and port your NodeCG instance is configured to use).

{
    "name": "test-bundle",
    "nodecg": {
        "mount": [
            {
                "directory": "custom-dir",
                "endpoint": "my-mount-endpoint"
            }
        ]
    }
}

The above example will make the contents of nodecg/bundles/test-bundle/custom-dir accessible via http://localhost:9090/bundles/test-bundle/my-mount-endpoint. These endpoints behave similarly to how Express' static method serves static files from folders.

For example, if custom-dir contains a file called hello-world.html, that file can be accessed via the URL http://localhost:9090/bundles/test-bundle/my-mount-endpoint/hello-world.html.
