Subject: [PATCH] name contains uppercase letters. get file object error.

With the simplest usage, a single file might be submitted like:
<input type="file" name="userFile" />

Controller code :
$file = $this->request->getFile('userFile');

so. $file is null.

FileCollection file Line 182,
$this->files[$name] = $this->createFileObject($file);

$name not be converted to lowercase.
