Added novaPageIndexQuery to StaticResource to mimic indexQuery

[GarethSomers]

I've added a method novaPageIndexQuery to Whitecube\NovaPage\Pages\StaticResource which allows someone to manipulate the Whitecube\NovaPage\Pages\Query on the nova index page. It's intended to mimic the indexQuery method.

I've also added the methodWhitecube\NovaPage\Pages\Query::sortBy to allow simple sorting.

It might work better just having a generic callback (e.g. $query->setCallback(...)) which gets applied to the Collection in Whitecube\NovaPage\Pages\Query::get.

Should merge in conjunction with #45 merged

Closes

#44 (sorta)

Usage

Configure your own config novapage.default_page_resource in config/novapage.php

    'default_page_resource' => \App\Nova\Page::class,

<?php

namespace App\Nova;

use Whitecube\NovaPage\Pages\PageResource;
use Whitecube\NovaPage\Pages\Query;

class Page extends PageResource
{
    public static function novaPageIndexQuery(Query $query)
    {
        return $query->orderBy(function ($item) {
            return $item->getTitle();
        }, 'ASC');
    }
}

Hi @GarethSomers,

Thanks for the PR. It seems good to me, I just found two little points I'd love to see enhanced :

• Could you add & document the 2 new configuration keys into src/config.php ?
• As shown in my previous review comment, the configuration values could not exist when upgrading an existing Nova project, meaning we should provide default values on lines 58 & 59 of src/Pages/Concerns/QueriesResources.php.

Thanks !

Both config() calls should default to the provided Resource classes in case the config file does not (yet) contain the default_page_resource or default_option_resource keys in order to ensure update compatibility.

Hi @Nyratas I've added documentation docs/README.md and I've set the default values in src/Pages/Concerns/QueriesResources.php .

Let me know if there's anything I've missed. Thanks!
