&UpdateStats($env, $branch, $type, $value, $other, $itemnumber,
$itemtype, $borrowernumber);
Adds a line to the statistics table of the Koha database. In effect,
it logs an event.
C<$branch>, C<$type>, C<$value>, C<$other>, C<$itemnumber>,
C<$itemtype>, and C<$borrowernumber> correspond to the fields of the
statistics table in the Koha database.
If C<$branch> is the empty string, the branch code will be taken from
C<$env-E<gt>{branchcode}>.
C<$env-E<gt>{usercode}> specifies the value of the C<usercode> field.
