Typo Upper/LowerCase

[Sanzzes]

Your Version fails with Kohana V3.3.
So you must rename all Variables/Files to right Case.

Kohana 3.3 is case sensitiv so when you call the Class Captcha and the file is named captcha.php it will fail.

To Fix -> rename the file to Captcha.php so Kohana can find it.

Obsolote and not working anymore:

In Word.php under classes/Captcha line 22 Kohana:Config is not longer exist in 3.3 and is now -> Kohana::$config->load('captcha.words')

In Line 29 -> utf8::strlen($word) change it to UTF8::strlen($word) in fact case sensitive writing.

I am no longer actively working on kohana-captcha. But if you would like to fork it and submit a merge request to fix these issues I would happily merge it.
