Bundler Enhancements

This adds the following features to Bundler:

  *  Compiling mustache templates to javascript via hogan
  *  Bundling entire folders into a single minified file
  *  Including directories in `.bundle` files
  *  Preferential ordering of javascript files within bundles using the `directory` or `folder` options
  *  The option to specify an output directory for computed files.

This also adds integration tests with jasmine-node, both back filled for features touched and newly implemented features.
