Upgrade nodejs version from 0.6.18 to 0.10.32

Based on m limited knowledge, I tried as much as I can to make this module install newer version from nodejs (0.10.32). Please review and validate.
@wassimsalib You're probably looking for https://docs.puppetlabs.com/puppet/latest/reference/lang_classes.html#using-resource-like-declarations . This is how you can have the nodejs module manage the repository for you without affecting other users of the module.
