Support for base URL in mellow about mellow

[devster31]

I wonder if this line:

Mellow/src/web/WebServer.js

Line 49 in 46a6d80

this.app.use('/', (req, res, next) => {

could be changed to allow a base url.
With something like:

const BASE_URL = process.env.BASE_URL || '/';

// ...

            this.app.use(BASE_URL, (req, res, next) => {
                req.webserver = this;
                if (req.cookies.token) req.headers.authorization = req.cookies.token;
                next();
            }, router);

//...

Not sure if there are other places where the root path is used though.

This should probably work. I'll look into it and add it.
