'can-reorder 'can-close 'new-button

The documentation mentions 'new-button, but the implementation does not yet support it. Fortunately I can add it to my application in other ways, so perhaps a quick update to the doc is all that is needed?

Whoops, I closed this prematurely. I've changed the contract to allow 'new-button, but need to implement the hook still.

[Bogdanp]

OK, I've now pushed a change to handle the new button event. The action on tabs can now receive 'new events as well.

Thanks!

Tangentially, I did learn from @mflatt (https://github.com/mflatt) that on macOS 'can-close only works with 'no-border, and it appears you cannot close the last tab, so depending on the desired behavior this may be another of those "add this behavior in other ways."
