Title: Fix compilation with clang under OS X

Trying to compile with clang under Mac OS X 10.8 (XCode 4.5) results in the error:

`assigning to 'objc_object *' from incompatible type 'DockIconClickEventHandler *'`

clang seems to be much more picky than gcc about the type a variable it assigns an Objective-C instance to, and a simple `class objc_object` doesn't cut it.
