- Validation of human (CAPTCHA).
  - self creation of account (e-mail address as username).
  - choice of CAPTCHA:  original (Authen::CAPTCHA) or newer reCAPTCHA (requires)
    DC to create account with http://www.google.com/recaptcha/, or not used.
  - Routines to generate CAPTCHA input and validate response moved to loncommon.pm
    to facilitate re-use.
  - Domain configuration for self-creation of accounts allows DC to choose which
    CAPTCHA option to use.
- CPAN module: Captcha::reCAPTCHA now needed. rpm being added to msu/testing repos,
  and dependency included in LONCAPA-prerequisites 1-21.
