Release new version to the Forge

It'd be great to have a new version in the Forge, 0.2.0 is too old. 

I have added 2 commits, one to release 0.3.0 and another one to easily push to the forge with puppet-blacksmith just running `rake module:release`

You need to configure your credentials in ~/.puppetforge.yml
