DeskTop: Allow selection in list views

This constitutes two changes:

* Adds support to IconTK for a "small icon" flag where the icon is
  in-line with and the same height as the label.

* Reworks DeskTop to use "small icons" for the list view, effectively
  as an overlay on top of the other columns.

Because all views now have icons, this actually removes many special
cases and saves bytes in main memory.

Room for future improvement:

* Selection is lost when changing view type. This is not a regression
  since it was previously lost anyway, but would be nice to fix.

* Renaming an icon when View > by Name is selected causes the window
  to refresh to reflect the new sort order. Ditto.

* Now that list views are not useless, it would be nice to
  save/restore the view type in addition to the window bounds across
  restarts.
