executed on slave causing double executing.

How to repeat:
Code review.

Documented fix in 5.1.18 changelog. Documented associated feature changes in Events, INFORMATION_SCHEMA, and Replication chapters of 5.1 Manual.

Updated synopsis, since the solution wasn't to disable CREATE EVENT itself, but rather make sure that the event was created but not executed on slave.
