Node.js: Use preferGlobal for npm installation script

[Former user]

When a Node.js package.json includes the following property

"preferGlobal": true

Your installation script on the module page should be like

npm install <module-name> -g

References: http://browsenpm.org/package.json#preferGlobal

Examples: https://www.npmjs.com/package/versioneye-update / https://www.versioneye.com/nodejs/versioneye-update/1.0.2

This is implemented already. For all new crawled versions VersionEye is evaluating the preferGlobal attribute from the NPMRegistry. See here https://www.versioneye.com/nodejs/versioneye-update/1.2.1 for example.
