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.
