Support the `log` role

See the description here
https://developer.mozilla.org/en/docs/Web/Accessibility/ARIA/ARIA_Techniques/Using_the_log_role

on the website where I use it, I get an error message with ARIA DevTools

Unsupported role: log (tag: div)

Hi @pcorpet, sorry for the late response.

I had to focus on other things recently but will take a look at this next week.
