Handle different data structure without key value labels

[IngaFeick]

The following data structure should be supported as input aswell:

"awesome_list" => [ { "animal" => "horse"} , {"food" => "bacon"} ]

expected outcome:

"animal" => "horse"
"food" => "bacon"

Maybe this should even be default behaviour, in case "key" and "value" are not set in the config.
