Pass only host to applescript

[otakustay]

Current implement of better-opn passes the entire url to openChrome.applescript to match an opened tab.

In some cases, when we debugging a web application, we navigate between urls and finally stay on another url that does not match the one passed to applescript.

This can especially happen when we set a specified url with some long pathname to better-opn, in our case it is host.com/login to ensure developers signed in first, but after that the url becomes host.com/some-module and cannot be matched against host.com/login.

We'd like to see an option to "loosely determine which tab to reuse" by passing only host.com to applescript.

@otakustay I think this is a legit use case.

Since this is a new behaviour, users should opt-in to use this new feature.

For the sake of keeping the interface consistent with open, instead of adding a new attribute to options, we can use an environment variable to control this behaviour, i.e

// open.js
require('better-opn')('http://localhost:3000/login')

# The env var name is tentative. I am opened to any better name
$ OPEN_MATCH_HOST_ONLY=true node open.js

Are you opened to contribute?
