/* Generic draft support for osTicket. The plugins supports draft retrieval
 * automatically, along with draft autosave, and image uploading.
 *
 * Configuration:
 * draftNamespace: namespace for the draft retrieval
 * draftObjectId: extension to the namespace for draft retrieval
 *
 * Caveats:
 * Login (staff only currently) is required server-side for drafts and image
 * uploads. Furthermore, the id of the staff is considered for the drafts,
 * so one user will not retrieve drafts for another user.
