Very basic AppEngine project

With not-very-tidied code from pervious main method
Basic scan (manual) and simple debug dump of data

Stores the info in app engine's data store in a probably totally
inappropriate format...
Very simple history url

And now automatically scan network front every 5 minutes

(Temporarily, this is running on my personal GAE account - I want
to see how much it costs!)
Use task queues to retry on scanning

And prepare for scanning multiple endpoints. Want to see how much this
costs before I do that though.
Upgraded to scala 2.10

My first real project in 2.10!
Factor out "Position" object
basic history aggregation
Implemented "history" table

This avoids complicated processing on read, and means
we write a whole lot less stuff to the datastore.
Now solely using history table

And scanning the top 5 fronts
