European flight data dashboard - updated to 2014

The main dashboard is now loaded with all of the data to 2014 - as much as Eurostat currently has.

Check the 'DataAvailability' tab for a rough indication of what's available.

Beware, the 2013-2014 numbers look to be twice the size of the 2012; Eurostat are looking into this as a potential upload problem (probably safe just to halve the values, for a rough estimate - and it means load factors & seats/flight are probably still correct).

I'll freeze APFlows now and work on a different view.
