Surprisingly, X-XSS-Protection is safer when disabled, and browsers are dropping support for it as a result. Because it's less safe to enable the filter, this change sets the default (and only) value to 0, instead of 1; mode=block.

This is a breaking change.

See #25.

I'll take a look.

Surprisingly, [`X-XSS-Protection` is safer when disabled][0], and
browsers are dropping support for it as a result. Because it's less safe
to enable the filter, this change sets the default (and only) value to
`0`, instead of `1; mode=block`.

This is a breaking change.
