Dave Pearson aad6d98aa5 More documentation tweaks (#2001 )

* Change the title of some widget references to their class names

The widget reference index had a slight mixture of widget title styles, some
being their class name, others being "written English" type titles. This
settles on the titles always being the class name.

* Add a link to the ContentSwitcher to the widget gallery

No screenshot for this, on purpose. By definition this widget isn't visible,
except via other widgets that it's enclosing and handling.

* Have mkdocs watch the main nav file

* Mark the content switcher off the roadmap
