Hardcoded non-encrypted websocket use

[vanhecke]

Running logstation behind an TLS proxy isnt possible, because the websocket is not encrypted.
Browsers do not allow usage of non-encrypted websocket over HTTPS-loaded pages.

Changing the ws:// to wss:// worked for me. But would be nice if this was automatic or configurable.

const wsurl = "ws://" + window.location.host + "/ws";
