Grunt server task throws errors, especially after a few repeated saves.

Getting tons of these errors lately, especially when editing css and saving often. Happens every so often when editing js files too.

Thoughts?

```

Start with the Grunt server task and its watch configuration, then reproduce the problem by repeatedly saving CSS and JavaScript files. Trace the reload handling reported around server/app/controllers/vendors.js and server/seed.js; done means repeated saves no longer produce EMFILE or readdir errors.
