 *  Where:

 *         N  = No, change status to not wanting an update.
 *         C  = Check (the default), check how many want an update.
 *
 * Sets/Unsets a nation flag.
 *
 * Only considers NORMAL, active countries.  No Deities or sanctuaries.
 *
 * After the change, send a message to the "tm" for it to check
 * if an update should occur.
