Cannot connect to the bridge when using host other than localhost

franchise/src/db/bridge.js

Line 13 in b541e65

const BRIDGE_URL = 'ws://localhost:14645';

This line needs to take into account whatever host was set when running yarn start --host=MYHOST_IP

Otherwise, it's nothing but a nice web app that can run locally only.

Nice work though!
