Upgrade dependency Racer

[kolegm]

Could you upgrade Racer for Derby to the last workable version 0.9.15?

Now it is v0.9.0.
And as I figured out, you have improved many features inside Racer.
Would be great to get them inside of Derby.

Thanks in advance!

The dependency in derby is "racer": "^0.9.0", which by semver rules will pick up all patch revisions, including the latest racer@0.9.15.

With NPM, you can see what version your app has installed by running npm ls racer. If you still have the older version of Racer, it may be due to a package-lock.json in your app, which you can update via the normal means, e.g. npm update.
