[Koha-patches] [PATCH] Bug 4866 for 3.0.x (Enable Change event for item plugins)

[Marcel de Rooy]

A few lines of code in additem.pl make it possible to add the Change event next to Blur and Focus for item plugins. This prevents running the plugin if the data has not changed. Patch sent for 3.0.x.
