Pushing changes to npm package

[ruchitrami]

This PR is merged but not available with the npm package. Would be great to push latest version to npm package.

Thanks @ruchitrami I'll take a look at pushing this to NPM. It's not merged into master yet, so I'll do some validation to make sure it's OK. It also updates to the latest version of XTerm which may be a breaking change for some so will need to major version it up. @farfromrefug any issue with this change?

@lukevp honestly do what you think is best. Don't really work on react those days ;)
