Title: Soak up nulls in RequestAnimationFrame.coffee

Components are evaluated when commands such as `noflo list .` are used. `window` doesn't exist at this time, so the entire process fails. It's probably advisable to `try/catch` as each module is evaluated for display.

Anyhow, this works around the problem sufficiently well.
