Cleanup HTTP APIs, update ports to avoid gap, rustfmt

Moved the HTTP APIs away from the REST endpoint abstraction and
to simpler Hyper handlers. Re-established all routes as v1.
Changed wallet receiver port to 13415 to avoid a gap in port
numbers.

Finally, rustfmt seems to have ignored specific files arguments,
running on everything.
