    Issue #255795 by Liam Morland: Add CAPTCHA to all forms by default

Issue #2021759: When user submits a correct answer, captcha module stores in session unconditionally, disabling page cache unnecessarily

Issue #1002246: make 'captcha_wrong_response_counter' updating optional and disabled by default, as it is expensive performance wise (clears variable cache)

Issue #472450 by ahwebd and soxofaan: add option to render image CAPTCHA code on RTL-mode for RTL languages

Issue #1460538 by neochief: avoid 'Call to undefined function _captcha_required_for_user' issue on cached forms

Issue #1597970 by drupalishsandip and soxofaan: PHP sucks at comparing strings that look like numbers

Seriously: string comparison ("123" == "0123.") is true in PHP

Fixed some internal drupal urls (admin/config/development/performance, admin/structure/types and admin/people/permissions)

Issue #893810: refactored captcha_form_alter to make sure CAPTCHA's are also shown on login block on (forbidden) admin pages when needed

Issue #780206: add a warning on performance settings page about disabled page caching on pages with a CAPTCHA element

Issue #1024370: only use $form_state['captcha_info'] cache after submission (e.g. comment/node previewing)

On some forms $form_state can be cached across requests, and the CAPTCHA info in there should not be used during form building before submitting.

Revert "Issue #1024370 by soxofaan, nineLemon, Pancho, slashrsm: Prevents CAPTCHA from failing in certain forms"

This reverts commit f56d53ec.

It was a wrong solution and caused other problems (e.g. Issue #1328272)

GD library availability check should look for imagepng function (which is required), not imagejpeg (which is optional). Related to issue #1337366.

Issue #1024370: Make sure we can use a top level form value $form_state['values']['captcha_response'], even if the form has #tree=true.

Issue #976436 by matheusgorino, soxofaan: Adds an ob_end_clean to prevent the output image from being corrupted.
