Update reactive-style; renamed to style-it to match api

[buildbreakdo]

Left '*' as the version in the package.json because I don't want to come back to update it, have a test that covers the button scenario in this project. Cheers

hey @buildbreakdo, thanks for you PR.

if you don't mind, I would ask you to specify the version number to reflect the features in the readme and avoid breaking the example in the case of changes.

thanks!

Thanks for the feedback, matched the versioning style in the radium package.json
