This is now "feature complete". Need to:

• write docs for the networking types
• Figure out whether I care about making the type-less APIs on Storage accessible only through a trait that marks them as internal only. Because the APIs cross crate boundaries, I can't make them truly private APIs. Users really shouldn't use much outside fo the Connection and ServerConnection traits.

Things left as of this morning's review process:

• Add server configuration
• Write server example
• Write server documentation:
  • trusted-dns
  • websockets
• Add integration-style test with multiple clients.
