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 Change-Id: I7625f861435a99ce3d7a2b1ece9731aaab1776f8
