add hooks for tweaking how downloads happen (for grist-static) (#665)

This makes three main changes:
  * Adds a hook to transform download links.
  * Adds a hook to add an externally created ActiveDoc to a DocManager.
  * Rejiggers XLSX export code so it can be used without streaming,
    which is currently tricky in a browser. Regular usage with node
    continues to use streaming.

With these changes, I have a POC in hand that updates grist-static
to support downloading CSVs, XLSXs, and .grist files.
