Support different mount-point / path for webserver

[SpraxDev]

I'm currently trying to setup a couple of warriors using the official Docker images.
I wanted to host all of them behind one convenient domain like warriors.example.com/reddit/ using nginx as my reverse proxy.

This already works for the assets loaded but seems to break for the SockJS-Script.
It is requesting /info instead of /reddit/info in my case (same goes for /api/all-projects).

The problem seems to be at

seesaw-kit/seesaw/public/script.js

Line 2 in 2dc0bad

var conn = new SockJS(window.location.protocol + '//' + window.location.host);

and got introduces in fa11921.

I couldn't find any reason for SockJS getting a custom built URL in the first place instead of just providing the current URL. Maybe adding the current path or using the current full URL would work here as SockJS already preprocessed the given URL?
(var conn = new SockJS(window.location.protocol + '//' + window.location.host + window.location.pathname);)

seesaw-kit/seesaw/public/sockjs-0.3.js

	utils.amendUrl = function(url) {
	var dl = _document.location;
	if (!url) {
	throw new Error('Wrong url for SockJS');
	}
	if (!utils.flatUrl(url)) {
	throw new Error('Only basic urls are supported in SockJS');
	}
	// '//abc' --> 'http://abc'
	if (url.indexOf('//') === 0) {
	url = dl.protocol + url;
	}
	// '/abc' --> 'http://localhost:80/abc'
	if (url.indexOf('/') === 0) {
	url = dl.protocol + '//' + dl.host + url;
	}
	// strip trailing slashes
	url = url.replace(/[/]+$/,'');
	return url;
	};

To fix the /api routes it should be possible to just let the browser handle everything and calling a relative uri at
