Fix ORDER & LIMIT argument type casting.
Bind integers as 'PARAM_INT' when running query - prevent explicit int values (such as in ORDER or LIMIT) from being quoted.
Fix 'update' where $data and $where fields have the same column
Merge array of $data and $where in update will result in omitted data if $data and $where fields have the same columns. Updated to append all passed values, so same columns in $data and $where will now use both values.
