Optimized data aggregation.

Browse source 
- All aggregation use only the raw data as input.
- Only produce aggregated data that will show in a chart (less work after clearing the sensor_data_aggr table).
- Adding version handling of data aggregation to secure that the peer has up to date data.
- New db version: 6 - Adding sensor.aggr_version(int, default=1), will clear sensor_data_aggr for local sensors
