APIv2 swagger json out of sync

[miklesw]

APIv2 is returning messages in an attribute called Items, whereas the swagger json has a messages attribute.

type messagesResult struct {
	Total int            `json:"total"`
	Count int            `json:"count"`
	Start int            `json:"start"`
	Items []data.Message `json:"items"`
}

If I change the attribute in the swagger json to "items", there are other issues with the actual message attributes too.
