Instead of just copying file from source to destination; now we copy all files/directories recursively. This will help us move sub folders and files from asset folders to public folder. Calatrava build tasks error out right now if you place sub folders.
Incremented jasmine-node version to 1.5.0, which is a newer stable release as the older version was incompatible with latest version of node.
