Breaking: #68010 - T3Editor - Event callbacks for codecompletion have changed

See Issue #68010

Description

Due to the rewrite of T3Editor to jQuery, the event callbacks for codecompletion have changed.

Impact

Plugins for codecompletion written in Prototype will not work anymore.

Affected Installations

Every third-party extension providing a T3Editor plugin extending the codecompletion.

Migration

Port the plugin to an AMD module. The event callbacks are now part of the module object and not a standalone function anymore.

Example code:

CoolPlugin.afterKeyDown = function(currWordObj, compResult) {
        CoolPlugin.somethingFunky(currWordObj, compResult);
};
