Date option default expects timestamp, docs state Y-m-d formatted string

@AaronOverton
you should use date function like this
date('Y-m-d', time())
Reference: http://php.net/manual/en/function.date.php

$tab->createOption([
    'name' => 'Report Date',
    'id' => 'hidden-report-date',
    'type' => 'date',
    'default' => date('Y-m-d', time())
]);

This pull request has the support for that date format default input with a couple of other update.

@tojibon Can you resubmit the PR for the date issue only?
