Add option to use turbo-stream over existing turbo channel websocket

[tleish]

closes #21

A few changes here.

turbo-stream reload method

With these changes you can now reload the page using the turbo channel by sending a turbo-stream to the client by setting:

config.hotwire_livereload.reload_method = :turbo_stream

Note: :action_cable is the default value.

This allows the gem to be used with AnyCable and JWT identification, however it can also be an option with just ActionCable.

When enabling the turbo-stream option:

• No hotwire-livereload ActionCable channel is created
• A different partial is rendered from the hotwire_livereload_tags helper
• A different JS file is loaded

Extracted Shared JS Code

This PR extracts some shared javascript into a separate file to be used with either option.

Turbo.visit action: replace

This PR also includes a change with reloads the page without advancing the history.

- Turbo.visit(window.location.href);
+ Turbo.visit(window.location.href, { action: "replace" });

Great workaround for AnyCable 👍
