therubyracer dependency

[KRaymundus]

I am trying to make this gem work in a windows environment. This gives trouble when installing the 'therubyracer' dependency. I see two options:

1. The first answer on this question says there is no way to install the therubyracer gem on windows, but I found a build for windows here. The problem is: this build is version 0.11.0beta. ng_classify requires 0.12. Is it possible to make ng_classify work with this version?

2. Here I found: "On windows gem 'therubyracer' is not required as it is used to provide the runtime environment and runtime environment already supports on windows". So maybe using :platform is an option to include the therubyracer gem only on non-windows platforms?

That's interesting. Never thought of that before but at the same time I don't have a Windows machine to this on. Thanks for your feedback will look into fixing when I have more time.
