This was suggested by Paul Argentoff [argentoff@rtelekom.ru] on the old feature request tracker at SourceForge. Can't
remember if we've already implemented this so I'm reporting it again.

It would be useful if FXAccelTable#addAccel() could somehow be extended to use code blocks, so that instead of always
specifying a target object and so forth, you could just attach a block (as with the connect method, or the extended
versions of FXApp#addTimeout).
