`on_change=` cannot have a block

Hi :wave: ,

Thanks for putting the effort into such a neat library!

None of the examples are currently building on 0.26.0, due to this compile error:

commenting out # def on_change=(&block : FontButton ->) # self.on_change = block # end from src/hedron/ui/font_button.cr allows compilation, but I'm not really sure that's a long-term solution.

I fixed it in a recent commit, I haven't pushed it yet. Will do so tonight.
