4.0.0

• Breaking: Forked reload to express-browser-reload which focuses exclusively on the Express use case, as opposed to reload which is a more generalized tool with more features beyond the Express world.
• Breaking: Altered the architecture to attach the WebSocket server to an existing Express server rather than creating a new server to run alongside it.
• Breaking: Removed support for some older browsers as well as checks to see if you're running an older browser to simplify the code and make it easier to maintain.
• Breaking: Removed all params except for route.
• Added a new param skipDeletingConnections which will skip purging HTTP connections on the Express server when it restarts. If you're already handling this on your Express server yourself, set this param to true to prevent errors.
• Refactored the code to make it simpler and easier to maintain.
• Updated dependencies.
