Summary: Currently, Celerity map rebuilds on Windows don't put Stripe or Raphael into the map. Move them into `webroot/rsrc/externals/` so they get picked up. At some point we should maybe let the mapper load resources from mulitple locations, but this is more straightforward for now. See https://github.com/facebook/phabricator/issues/294 Test Plan: Rebuilt map, verified Burnup Rate + Stripe work.
