-----
* added shortcut for AQL ternary operator
instead of `condition ? true-part : false-part` it is now possible to also use a
shortcut variant `condition ? : false-part`, e.g.
FOR doc IN docs RETURN doc.value ?: 'not present'
instead of
FOR doc IN docs RETURN doc.value ? doc.value : 'not present'
* fixed wrong sorting order in cluster, if an index was used to sort with many
shards.
