Allow translatable title for the CAPTCHA in the form

I created a patch to allow translatable title for the CAPTCHA in the form

https://plugins.trac.www.ads-software.com/ticket/1860

This is my first patch for a WordPress plugin and I wasn’t sure of the proper way to submit a patch.

I hope a link to the ticket is good enough because I was not able to find the CAPTCHA plugin in the list of components in the bug tracker.

thanks
