linux binary on a staging server still pings localhost for watch-editing

[hyphae-lab]

Maputnik version: linux binary: maputnik version Editor: 1.7.0; Desktop: 1.0.7
Browser: Chrome
OS: macOS

Description of the bug:
The linux binary won't watch/edit style even if all permission groups are allowed to write on AWS Ubuntu
An error that says "GET http://localhost:8001/styles net::ERR_CONNECTION_REFUSED"
It seems like the Javascript embedded hostname is localhost and it is not able to ping back the server from the browser.
Also, it works just fine on my local machine where the host IS localhost.

Steps to reproduce the behavior:

1. Download latest linux binary from github page
2. Unpack zip
3. Run ./maputnik --port 8001 --file ./style.json --watch
4. Load editor in browser
5. Change map
6. check if style.json has changed

Style file or style URL:
(http://ec2-54-188-62-113.us-west-2.compute.amazonaws.com:8001/#0.55/0/0)

Screenshots:

Hi @hyphae-lab I did some digging around the code, and it appears you can add two URL parameters to resolve that: localhost and localport. Here is the relevant code.

Are you able to test this? http://ec2-54-188-62-113.us-west-2.compute.amazonaws.com:8001/?localhost=ec2-54-188-62-113.us-west-2.compute.amazonaws.com&localport=8001#0.55/0/0

I'm not sure why the code does not default to whatever host it is on. It does seem to do that for port.
