Hi, and thanks for reading!  
I hope you like ATptcha and use it...I am!

Sometimes you might want a Captcha in an AT, and rather 
than futzing with base_edits form controller tragedy, you
can now just add a captcha widget.  If you want to use
a Captcha in a Page Template, you do NOT need ATptcha.
PloneCaptcha does this out of the box.

This may be a bit strange in implementation, because the
value of the field is written to your type (irrelevant)
and will show up if you re-edit the object, causing the
user to have to re-captcha.  Ah well, it's not perfect,
but it's better than a spam-filled site.

NOTES:

The validator gets called twice upon submission.  This caused
problems when getting things from the REQUEST for validation.
Search for XXX to see what I mean.  Not sure if this is a 
security problem, but I don't think see how it could be, but
might enable a crafty person to avoid the Captcha (??)

            widget = CaptchaWidget(
                description="This helps us prevent automated spamming.",
                label="Verification Code",

Thanks to the folks who wrote Captcha, PloneCaptcha, and optilude, 
whose code I used as a template for this widget, and for everyone in
#plone IRC who helps me out and puts up with my wisecracks.
