Fix right-clicking delegates again

I accidentally broke this while trying to dance around the two new
overlapping TapHandlers, but this didn't work. What ended up happening
is that you couldn't right-click non-message delegates anymore (such as
images, files, etc.)

I *still* couldn't figure out how to get overlapping TapHandlers to
work, so I just switched to a MouseArea instead. This makes everything
work as expected now.
