Operations content returned in array. Update key value fix.

Content values are now returned as an array instead of a dictionary with 'values' as the key. I heard a few groans about there being to much to parse in the returned set of data.

Also, I adjusted how key values are updated to function more like the post call. I was getting "integer not iterable" errors when a key's value was a standard int. This change allows for updating keys by passing in a dictionary of 'keyvals' in the same manner as posting them.
