captchta_helper and Severity: Warning --> unlink(./captcha/fonts) Is a directory

[Lechus]

I think it's something to be fixed by replacing
if ($filename != "." and $filename != ".." and $filename != "index.html")
to
if ($filename != "." and $filename != ".." and $filename != "index.html" and $filename != "fonts")

I have updated the code to check if the file is a .jpg file since that are the files that are generated by the captcha helper. Previously the code only ignored, '.', '..', 'index.html' filenames. It would also try and delete a subfolder that may have contained the font_path.
