Shorty Tracking

This Shorty Tracking package implements an app for the ownCloud web application. It plugs into another app, the Shorty package and enhances that with additional features:
- detailed tracking of all clicks refering to Shortys
- visualization of all clicks registered for a Shorty

The app does not register any own settings or preference dialog nor a separate navigation entry. Instead it adds an additional action icon (sparkline) to every Shorty that exists in the main Shorty app.
