The big fat bernie revamp! Er, big fat miso revamp rather:

- Combined SceneViewPanel and IsoSceneView into one happy panel.
- Ditched the DisplayMisoScene notion; the new MisoScenePanel now manages
  resolved scene information (like base, object and fringe tiles) itself
  so that it can...
- ...support scrolling scenes by keeping blocks of resolved base, fringe
  and object information loaded only for what is potentially visible
  rather than for the whole scene.

Other things were surely cleaned up or broken in the process to keep a
keen eye out.
