Feature/raw data tab

To all sequential components, like rows in a table, we should provide react key, e.g.
(om/build (data-row raw-data table-id) row {:key :type}).
The key is the unique identifier for that component. It's a bit tricky with the sensors as we don't have a single unique key, we combine device_id and type. But having react key will get rid of the warnings we see in the console and will prevent from potential problems, see: https://coderwall.com/p/jdybeq
