Ticket #298: Enhance fValidation to check $_FILES as well as regular fields

I'm uploading data to a table. My form has 2 fields: database_table, and data_file (file upload type). I'd like to be able to validate both at the same time this way:

$validator = new fValidation();
$validator->addRequiredFields('database_table', 'data_file');
$validator->validate();

This currently doesn't work, but it would be nice if it did.
