   Table containing rating-changes done by admin.
   Needed because rating-changes need to be taken into account
   on rating-recalculations.

   Possible rating-changes are reset of confidence-interval relative to rating,
   and change of Players.Rating2 itself. Reset of confidence-interval will apply
   after rating-change (if there is one, see Changes-field).
