Added navigateFromTile to the IQueryOperations API. This replaces the existing sequence of

1 navigating from the original tile to the nearest featured tile then
2 finding the entry for the feature nearest its centre (all with the AtlasDAO)

with a single call to the QueryTool. It's more efficient but less predicable - you'll get one of the features from the destination tile but not necessarily the one nearest its centre. We still achieve our goal of moving n tiles east until we hit something and we get there quicker - have to get user feedback on whether people feel disorientated.
