Managing rake and bundler packages. Rake and bundle resources.

The intention is to have the ruby module manage the installation of the rake and bundle tools, and provide resources for executing rake and bundler tasks. It's a bit hard to do rake and bundle tasks in the abstract without having specific knowledge of how bundler or rake are installed, e.g. you need to make the `require` OS specific for the bundler package... which will fail if they were installed by a virtual package.
