Andy McFadden 365864ccdf More progress on visualization
Implemented Apple II hi-res bitmap conversion.  Supports B&W and
color.  Uses essentially the same algorithm as CiderPress.

Experimented with displaying non-text items in ListView.  I assumed
it would work, since it's the sort of thing WPF is designed to do,
but it's always wise to approach with caution.  Visualization Sets
now show a 64x64 button as a placeholder for the eventual thumbnail.

Some things were being flaky, which turned out to be because I
wasn't Prepare()ing the plugins before using them from Edit
Visualization.  To make this a deterministic failure I added an
Unprepare() call that tells the plugin that we're all done.

NOTE: this breaks all existing plugins.
