Updated versions, fixed bower and karma includes.
Adjusted clock event visualization to new architecture for getting records. Cannot rely on an app to store date and type fields, so the visualization is now preprocessing the records. Closes #4.
Updated Jawbone UP app to import data for a given date range and create one record per endpoint per day. Removed need to call Node module for that, but added backend functionality to serve as a proxy for sites (like Jawbone) that don't allow the browser-based javascript to import directly. Also added authorization tokens for apps, which closes #27. Updated dump with sample data.
