adds v0_10_3 manifest

Adds manifest for Node v0.10.3 as recommended by @wfarr in boxen/puppet-nodejs#4.

I did not bump the 0.10.x ["blessed" version](https://github.com/boxen/puppet-nodejs/blob/master/manifests/v0_10.pp). I'll leave the blessing for the priests until instructed otherwise.

Thanks!
