SeaSurf documentation link redirects to an error page

[Shellcat-Zero]

Hi,

The documentation link posted here on GitHub and on PyPi.org is redirecting to a 404 page, that is, links http://readthedocs.org/docs/flask-seasurf/ and https://flask-seasurf.readthedocs.io/ are redirecting to the non-existent documentation page of https://flask-seasurf.readthedocs.io/en/2.0.0/ which is a 404 page.

The correct page, as I found by digging through issue comments here on GitHub, should be https://flask-seasurf.readthedocs.io/en/latest/.
