FileInputValidator accept is not case insensitive

[nischi]

Hi @hackingharold

I realized that the accept Validator is not working like the accept attribute in HTML. The accept attribute is case insensitive but the accept Validator in FileInputValidator is case sensitive.

The parseAttribute function get the accept attribute value as lowercase and the check in isAcceptedByExtension works with endsWith which is case sensitive. So all files which has upper case file extension will be a wrong extension.

I will provide a pull request in the near future.

kind regards,
nischi
