AU Election 2013 block in Front

This allows the configuration for a Front to use the `RunningOrderTrailblockDescription` that is used in Facia. In doing so this will pull a specific collection from the Facia database.

It introduces a new class specifically for the case of having a switch around a `RunningOrderTrailblockDescription` with `RunningOrderTrailblockDescriptionSwitch`.

It also links query to configuredQuery in the override for `ConfiguredQuery`.

And to top it all off a switch called `AuElection2013`.
