Configurable port for Editor HTTP API

[selimanac]

Editor HTTP API is a great solution especially for 3rd party IDE integrations. I would like to use it with Sublime Text(or vscode)

Currently its port is random and there is only way to get the random port of the Editor's http-server is by looking at console output. There is a workaround, but it is problematic and it is not a proper solution.

it would be perfect, if the port number can be configured from editor’s preference window or before the Editor lauch(maybe by passing a param to Editor). But of course it requires a port check before starting http-server. If the port is in use it might use a random port
