Enhancement proposal feedback

I think the project could be improved adding convenience methods to the objects instead of passing id's through the relevant services.

Examples would be:

func (r *Room) History(opt *HistoryOptions)
func (r *Room) Message(msgReq *RoomMessageRequest) (*http.Response, error)

With a flow like:

room := client.Room.get("123")
room.History(&hipchat.HistoryOptions{})

This could be achieved by adding the service to the struct and then create some wrapper methods.

type Room struct {
	...
	GuestAccessURL    string         `json:"guest_access_url"`
	roomService       *RoomService
}

func (r *Room) History(opt *HistoryOptions) (*History, *http.Response, error) {
	return r.roomService.History(strconv.Itoa(r.ID), opt)
}

I would like to work on a PR for that but I can understand if that doesn't fit the projects vision.
