Use beautified form of Key ID

The only problem is that for a couple of these, I couldn’t figure out how to get to that screen to visually check the effect, but it was OK on all the ones I could try.  The beautified key looks a little better in a proportional rather than monospace font, and I couldn’t find the xml styling for the key ids in a couple places, most notably the encryption drop-down keyspinner.  But it still looks better than before.
