Make the CaptchEtat BotDetect style name configurable

MR pushed.

Could the 2.0.x-dev branch be made public so we can associate new issues with the right version? Only 1.0.2 available at the moment.

Thanks.

Hello @mably,

I am releasing a new version for this module.
I will leave the current version working only with webfroms.
And the version 2 will be the one that you worked on, integrating captchetat with captcha.
