cocoa: Avoid warning related to multiple handleEvent: definitions

Avoid compiler confusion as to which method signature to use for the
handleEvent: selector on OSX >= 10.6 by making the variable type-safe
as opposed to generic 'id' type.
Requires moving the variable definition to after the class definition.
