Remove leftover info from package.json
Fix bug with symlinking node_modules
  running grunt shell:setup when a subdirectory already has
  a symlink to node_modules creates another symlink to
  node_modules in the actual node_modules directory

  Able to fix the issue, but at the cost of the most unreadable
  abomination of a shell command I've ever made (largely due to
  limitations of grunt-shell)
