Move all web assets to shared cached space

Put all web assets including plugin assets under a shared static/ route
in the web interface that's declared as immutable and cacheable for 1
year.  This allows all JavaScript bundles to be loaded from disk instead
of having to check with the web server each time and significantly
speeds up the web interface load time.  It also fixes the public path
issue when using the --dev-plugin option behind a proxy.

To prevent collisions and stale data all assets now include a hash in
the filename.  This means the entrypoint is now dynamic and specified in
a manifest.json file created from the web build.  For plugins this means
the filename attribute needs to be removed from webpack.config.js.
