Add facia-scala-client dependency
Initial commit for change over to scala client, main changes;
 - Change from Map[String, JsValue] to TrailMetaData
 - Change over to facia client Collection type
Delete CollectionItem and fix mixing of types; We now request from
content API from String ID rather than CollectionItem / Trail /
SupportingItem
Change retrieveItemsFromCollectionJson to return Seq Trail
Change over to usage of MetaDataCommonFields for both types of meta data
