* Remember in PartitionMenuItem if a partition is a suitable install target.

* Show non-BFS partitions again, but show them disabled and show the content
  type in the menu label. BFS partitions don't get the content type shown, so
  that it looks more like the reason why they are disabled if the content
  type is shown.
* Small cleanups.
