New function: FOGBUGZ-LIST-STATUSES.
added View Status as a task.
Removed ORG-FOGBUGZ-DONE-STATUS-IDS, not necessary. Updated documentation for ORG-INSERT-TODO-FOGBUGZ.
New function: fogbugz-view-status. Changed how fogbugz-map-response works so that it can handle both view and list commands (one object or multiple objects returned).
