Add the support of the new Twitter's design:
- Prevent a tweet background blinking on the download button click.
- Add the support of triple images (They are tiny (less than 200 px) with the new design).
- Outdate "Topics To Follow" in the right column.
It looks that "Topics To Follow" was removed, I did not seen it for months.
Note: with the recent Twitter update the most of NSFW tweets are required to have an account. Hovewer, some tweets are still possible to expand beeing unloggined. So, "Expand Spoilers" option is still actual.
