Expected behaviour

Would like to install Karma in Node v7

Actual behaviour

NPM engines disable to install karma with node v7 in my project, but global it works.

Environment Details

• Karma version (output of karma --version): Karma version: 1.4.1

Steps to reproduce the behaviour

1. nvm install v7
2. npm install karma --save-dev
   npm ERR! notsup Unsupported engine for karma@1.4.1: wanted: {"node":"0.10 || 0.12 || 4 || 5 || 6"} (current: {"node":"7.1.0","npm":"3.10.9"})

I would like to know if we need to update the version support, since it allow to install as global and works.
