Form Label Setting Defaults

Allow users to adjust the form label placement for all future forms.

Should look something like this.

<?php
// Put this in your theme's functions.php or a functionality plugin
add_filter( 'gform_form_settings_defaults', function( $defaults ) {
    // Options: 'top_label', 'left_label', 'right_label', 'hidden_label'
    $defaults['labelPlacement'] = 'top_label';
    return $defaults;
});

We should probably skip hidden_label as an option because that would default all future labels to hidden which is not what most users would want.
