Load plugins & .DS_Store on Mac

[rakanalh]

Just faced this problem with the "loadPlugins" method inside phpThumb class. It was including a folder that is automatically placed inside the directory in which this class resides called ".DS_Store".
Inside the loop in which you read all the plugins you check for ".", ".." and ".svn" but i suggest checking if the current file is not a PHP file

I've modified the code in my project to be:
while (false !== ($file = readdir($handle)))
{
if(substr($file, -3) != 'php') continue;
include_once($pluginPath . '/' . $file);
}

As the previous one was causing a problem having the image to show because of the output caused by including ".DS_Store"

Hope you fix this issue in some other more flexible way :)
