Add target-of-target (ToT) mini frame below target frame

Browse source 
Shows the name and health bar of whoever your current target is
targeting. Reads UNIT_FIELD_TARGET_LO/HI update fields which are
populated from SMSG_UPDATE_OBJECT. Frame is positioned below and
right-aligned with the main target frame.
