Add all routes the web interface is served on to the express app and
serve the index.html file on. Due to the index html not knowing which
path it's hosted under, a path to the root of the web interface is
replaced using string substitution from the master server.
Set up webpack for the master server's web interface and fix the issues
from the imported interface source files. The .jsx files in
package/master/web are bundled together into package/master/static and
served by the master server via express.
