Releases for CAPTCHA

This release is intended to be the last release candidate before a final CAPTCHA 6.x-2.0 version.

Feature-wise, the goals of CAPTCHA 6.x-2.0 are completed and there are no critical or outstanding bug reports left. However, I decided not to go for a final 6.x-2.0 version because of the following.
This 6.x-2.0-RC3 release is the milestone where the CAPTCHA 6.x-2.x branch becomes the recommended branch for Drupal 6 and the 6.x-1.x branch becomes deprecated (it was already unmaintained for many moons). Switching the "recommendedness" on a release candidate is mainly to increase usage of the 6.x-2.x branch (which is now roughly at 5000) at the expense of the 6.x-1.x branch (which is now roughly at 22000), collecting more feedback and possibly work out some more kinks before the final CAPTCHA 6.x-2.0 version.

Changes since DRUPAL-6--2-0-BETA5:

• #463002: dropping the preprocess op in hook_captcha()
• hardcoded CAPTCHA placement on comment_form: the 'Submit' button can be omitted on first submission, which confuses the automatic placement detection.
• fixed problem with CAPTCHA description still showing up after comment preview with correct CAPTCHA response and added test for this
• #467618: made CAPTCHA element placement more foolproof, e.g. when there are no buttons on a form
• added forum_node_form to the default form_ids on install
• fixed problem with node previews (CAPTCHA session ID was not reused, so no multipage form persistence)
• captcha_set_form_id_setting() now also accepts an object with module and type attributes
• #472144 by hctom and soxofaan: PHP error on CAPTCHA admin form submit when no CAPTCHA points defined

Changes since DRUPAL-6--2-0-BETA3:

Since CAPTCHA 5.x-3.1 was already more than one year old, it was time for a new release.
