Merge with BOTCHA

@AlexisWilke Let me invite you to our dream-team of non-CAPTCHA (ie invisible to end-user) spam fighters:

• iva2k (BOTCHA founder and maintainer)
• Dustin Currie (un.captcha.lous founder and former maintainer (un.captcha.lous merged with BOTCHA), BOTCHA maintainer)
• deeporange1 (JS Validate Forms founder and former maintainer (JS Validate Forms merged with BOTCHA), BOTCHA maintainer)
• Staratel (BOTCHA maintainer)

Don't you think that together we could do more than each alone? We miss you, AlexisWilke.

Here you are some points why you should join us:

• Highly configurable spam protection framework: Each way of spam protection is a Recipe, which has its own logic of form submission handling. Recipes are bundled into Recipebooks, which are applied to the forms. The list of available recipes: http://drupal.org/project/botcha#recipes-included. UI lets you to turn on or off recipe applying per each form. It helps to avoid critical situation when one or more recipes doesn't work as you like: you should just turn them off and post an issue to Drupal.org - and your site would not be affected by any discomfort.
• Selenium-tests for all major browsers (Firefox, Google Chrome, Opera, Internet Explorer plus possibility to extend): It means that JavaScripts-recipes work as expected - always, guaranteed. If you see something strange - you could just launch all Selenium-tests to see what's wrong and post an issue to Drupal.org. Brief Howto-instruction (both installation and usage of Selenium) is inside the Selenium-tests file.
• Fully test-covered: Tests covered almost every line of the code. Plus tests' structure has been unified - and now it is really simpler to maintain it.
• OOP-style: BOTCHA is moved to OOP-architecture. It means that all "entities" that take part in BOTCHA functionality are turned into classes. That gives more flexibility to extend and freedom to modify.
• Like MVC-application: The module's internal structure looks like real MVC-application. It gives a chance to separate logic of the application and the layer of interoperability with Drupal platform - that means that the BOTCHA is going to become more version-independent. I hope in the future we would see a Drupal-version-independent BOTCHA module. It eases maintainership of the module.
• Module as an Application: Each hook implementation is a method of Botcha class, which extends abstract Application class. Turning a module into a class gives a lot of opportunities, such as applying "Decorators" (see http://en.wikipedia.org/wiki/Decorator_pattern) to a module as a whole. For now we have Logger decorator implemented (Logs every method call into a file - for development purposes, turned off by default), Cacher is planned. See Moopapi project page for more details: http://drupal.org/project/moopapi.

Also let me respond to pros and cons from discussion in #840838: Hidden CAPTCHA v. Spamicide:

• I guess that the main difference is that my module requires CAPTCHA and thus prevents you from having a hidden CAPTCHA + another CAPTCHA. (at least in the current version you cannot include more than one CAPTCHA.)

  It is possible to use BOTCHA alone without CAPTCHA, BOTCHA does not interfere with CAPTCHA.

• The one benefit that I do not see in the other one is that CAPTCHA can count the number of times it misses.

  BOTCHA has its own statistics of successful and failed submissions. It is shown on Status report and on BOTCHA General settings. It could be reset at any moment by pressing a special button.

• And it sounds like spamicide auto-inject itself in all forms. Kind of a waste for all the Admin forms.

  BOTCHA presence is configurable via UI per form. A special option of UI "Allow BOTCHAs and BOTCHA administration links on administrative pages" handles BOTCHA appearance on admin pages (disabled by default).

• What I still would need to do is create a different CSS name on request and change the actual name of the input field (so robots cannot just learn those two things and not fill the field.)

  All field names are randomly generated in BOTCHA - so it provides maximum protection.
