Title: moved L10n to a ready() requirement, rather than a blocker for the polymer definition

This fixes Chrome Canary. Unfortunately, sync XHR is getting deprecated, so this is a monkey patch at best - this still works in Chrome and Firefox, but moving the requirement may cause timing issues on slower networks.
