Lotsa metrics + ionic deploy + workaround for tile loading issue

The theme for this release is: metrics!

• Metrics API that returns daily, monthly, yearly summaries of various metrics,
  both wrt local time filters and UTC timestamp ranges
• New metrics screen that shows trip count, distance and duration over time,
  split by mode. On the server, these are aggregate metrics - on the phone,
  they are individual metrics.
• Thanks to @krisma, in addition, we have more detailed common trip and common
  place screens that show metrics about typical start times and durations.

From a maintainability perspective, we have also integrated with ionic deploy
http://docs.ionic.io/docs/deploy-overview
which allows us to push UI changes without waiting for app store review.
You might see more prompts to apply UI-only changes in the future as the native
part of our code stabilizes and we focus on integrations and utility.

We also have several fixes in the phone code, including one which adds a button to workaround the tile loading issue.
