/**
 * @file status.h Status API
 * @ingroup core
 *
 * A brief explanation of the status API:
 *
 * PurpleStatusType's are created by each PRPL.  They outline the
 * available statuses of the protocol.  AIM, for example, supports
 * an available state with an optional available message, an away
 * state with a mandatory message, and an invisible state (which is
 * technically "independent" of the other two, but we'll get into
 * that later).  PurpleStatusTypes are very permanent.  They are
 * hardcoded in each PRPL and will not change often.  And because
 * they are hardcoded, they do not need to be saved to any XML file.
 *
 * A PurpleStatus can be thought of as an "instance" of a PurpleStatusType.
 * If you're familiar with object-oriented programming languages
 * then this should be immediately clear.  Say, for example, that
 * one of your AIM buddies has set himself as "away."  You have a
 * PurpleBuddy node for this person in your buddy list.  Purple wants
 * to mark this buddy as "away," so it creates a new PurpleStatus.
 * The PurpleStatus has its PurpleStatusType set to the "away" state
 * for the oscar PRPL.  The PurpleStatus also contains the buddy's
 * away message.  PurpleStatuses are sometimes saved, depending on
 * the context.  The current PurpleStatuses associated with each of
 * your accounts are saved so that the next time you start Purple,
 * your accounts will be set to their last known statuses.  There
 * is also a list of saved statuses that are written to the
 * status.xml file.  Also, each PurpleStatus has a "saveable" boolean.
 * If "saveable" is set to FALSE then the status is NEVER saved.
 * All PurpleStatuses should be inside a PurplePresence.
 *
 *
 * A PurpleStatus is either "independent" or "exclusive."
 * Independent statuses can be active or inactive and they don't
 * affect anything else.  However, you can only have one exclusive
 * status per PurplePresence.  If you activate one exclusive status,
 * then the previous exclusive status is automatically deactivated.
 *
 * A PurplePresence is like a collection of PurpleStatuses (plus some
 * other random info).  For any buddy, or for any one of your accounts,
 * or for any person with which you're chatting, you may know various
 * amounts of information.  This information is all contained in
 * one PurplePresence.  If one of your buddies is away and idle,
 * then the presence contains the PurpleStatus for their awayness,
 * and it contains their current idle time.  PurplePresences are
 * never saved to disk.  The information they contain is only relevant
 * for the current PurpleSession.
