display alternate checkmarks
Twitter now (for subscribers) displays check marks that nitter instances don't display. For an example, see:

Apparently, Twitter will roll out more colors and badges in the near future:

I looked through the summaries of recent commits, and didn't notice anything about displaying the new check marks, and I wonder if nitter has any plans to support their display in the future.
