Nonce integration

[MatzeKitt]

What feature are you requesting?

Currently, there is no nonce integration, so that it would be easier to send the same form multiple times. There should be an option to use nonces, which should be enabled by default.

It should indicate that it should only be disabled if you’re using a caching plugin. Maybe we can also detect major enabled caching plugins and disable that option in that case.

Why is this feature necessary?

Better spam protection.

Are you expecing side-effects?

Don’t make it optional and use Ajax to retrieve the nonce value.
