replace unit detail splitter with docks

- removes the splitter and table/tree layout from the details dock, and
replaces them with a set of dockable widgets (ie. unit skills,
attributes, roles, etc. docks)
- by default the details pane is configured with docks tabified, however
they can be closed, floated, dragged and dropped to other configurations
