Updated version of the toolbar example available for review and comment

I have moved my work on the toolbar to the W3C repository branch:
https://github.com/w3c/aria-practices/tree/issue541-toolbar-redesign


You can view the latest version of the toolbar at:

In additional to the example code changes we discussed at Monday’s meeting, I have made changes in the keyboard, role, property and state tables that need review.
