Expected Behavior

Try to refresh the current browser window

Actual Behavior

Open always a new tab

For Bugs; How can we reproduce the behavior?

For Features; What is the motivation and/or use-case for the feature?

Inspired on create-react-app solution.

Since I usually use Google Chrome, I expect to stay in the same (current) browser tab
when re-launch webpack-dev-server, instead of use a new one and close those more.

Just curious if the Webpack people/ecosystem are interested in having this behaviour (will PR in case), since is very specific to Chrome browser in OSX platform.

Furthermore, the solution requires to have an extra file .applescript in the package.

Thoughts?
