unlink exception during utpdated files cleanup

[Manvel]

Hi,
I was using your plugin for a while and noticed some exceptions
ErrorException [ Warning ]: unlink(/var/www/darth/html/wp-content/uploads/wp-less/my-theme/..): Is a directory

/var/www/wordpress-site/html/wp-content/plugins/wp-less/lib/Garbagecollector.class.php [ 118 ]

113 * @param array $files
114 * @return array
115 */
116 protected function deleteFiles(array $files)
117 {
118 return array_map('unlink', $files);
119 }
120 }

I've fixed the Error by adding:
$dir->setFlags(RecursiveDirectoryIterator::SKIP_DOTS);
for RecursiveDirectoryIterator to skip the Dots during iteration.

Here is how you can debug the exception:
Change the code on line 33 with:

try
{
    $this->deleteFiles($outdated_files);
}
//catch exception
catch(Exception $e)
{
   print_r($e);
}

Also would like o thank you for the plugin.

Yes, the unlink is causing an exception to be thrown because it cannot unlink the "." and ".." shortcuts on a unix based system.

My bad, I missed it (wish you can add as unread some PR or a better clue on the dashboard)

Thanks for the fix :-)
