Online documentation for Global XSS Filtering section

It shouldn't mention it at all on that page ... https://github.com/bcit-ci/CodeIgniter/c...0bb8c52f05

Of course removing it is even better.  However for consistency, you might want to scour the CI documentation for everything else that's deprecated so you can remove those too.

I did say "on that page" ... it just doesn't belong in there, arguably even if it was not deprecated. That doesn't mean deprecated functionalities should be completely removed from the docs.
