Running triggers on the slave for Row-based events

When one is using replication, they normally do not need to care about triggers. Triggers' actions are propagated to the slave:
- When one uses statement-based replication, binary log will contains SQL statements. Slave server(s) execute the SQL statements. Triggers are run on the master and on each slave, independently.
- When one uses row-based replication, binary log will contain row changes, it will have both the changes made by the statement itself, and the changes made by the triggers that were invoked by the statement.
