Objectives:
* Make it possible to add items to toolbars without having to have all
toolbars know about the items in advance
* Make it possible to specialize an existing tool and have it be used
instead of the base implementation
Approach:
* Tools are named using a path-style category/id/ext system, making them
selectable, the latter component being used to differentiate extended
tools from their base classes, but is ignored during selection
* Toolbars have ToolGroups, which include or exclude tools by category or
category/id, and order them by promoting and demoting selections of
tools by category or category/id
Future:
* Add a way to place available but not yet placed tools in an "overflow"
group
* Add a mode to ToolGroup to make the tools a multi-column drop-down style
list with labels so tools with less obvious icons are easier to identify
- and probably use this as the overflow group
