sspak-sniffter doesn't work with SS4 app object

[sminnee]

https://github.com/silverstripe/sspak/blob/master/src/sspak-sniffer.php relies on Core.php and global $databaseConfig. For SilverStripe 4 this will need to change.

Ideally, the pre-app-object support for SS4 will still work.

Our quick fix is:

} else if(file_exists(BASE_PATH.'/framework/src/Core/CoreKernel.php')) {
	//SS 4 OO
    use SilverStripe\Control\HTTPApplication;
    use SilverStripe\Control\HTTPRequest;
    use SilverStripe\Core\CoreKernel;
	
	require_once(BASE_PATH. '/vendor/autoload.php');

	if (!file_exists($autoloadPath = BASE_PATH. '/vendor/autoload.php')) {
	    exit;
	}

	require_once $autoloadPath;

	// Mock request
	$request = new HTTPRequest('GET', '/');
	$request->setSession(new Session([])));
	$kernel = new CoreKernel(BASE_PATH);
	$app = new HTTPApplication($kernel);
	
	$app->execute($request, function (HTTPRequest $request) {
		global $databaseConfig;
		$output = array();
		foreach($databaseConfig as $k => $v) {
		    $output['db_' . $k] = $v;
		}
		$output['assets_path'] = ASSETS_PATH;

		echo serialize($output);
		echo "\n";
		
	});
	exit;
} else {

The branch ss4rc1-compat works in Dev, but I have only tested the save command. Our sysadmins use sspak with Fabricdeploy so will ensure it works for their use-cases and report back...sometime.

Thanks to @mikenz that formed the basis of this.

This code seems to be very SS3 centric because there is no mention of

vendor/silverstripe/framework/core.php or something like that.
