[PATCH] -setTarget: and -setAction: enabled in NSImageView

[Kazunobu Kuriyama]

Hi,

Because no one gives me any solution to my problem on NSImageView,
I offer my own here. They simply makes NSImageView enable
target/action without raising an exception.

I hope these tiny paches fix the problem (at least for the
example source I mentioned).

I hope they do no harm to the rest of the library.
I would appreciate it if someone could confirm this.

        * Source/NSImageView.m (-performDragOperation): Let target call
        action.
        * Source/NSImageCell.h: The super class NSCell is replaced with
        NSActionCell.
