Added support for callback url

[mayankamencherla]

Added support for callback url.

[captn3m0]

As mentioned in the magento callback_url PR, the failure modes need to be handled in the callback URL, otherwise this breaks.

Pushed a fix for a variable assignment issue (callbackUrl), but there are still a few errors.

Notice:  Undefined variable: callbackUrl in razorpay-woocommerce/razorpay-payments.php on line 262

Please ensure that you have wordpress error display enabled. This is how my wp-config.php looks:

<?php
define( 'WP_DEBUG', true );

// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );

// Disable display of errors and warnings 
define( 'WP_DEBUG_DISPLAY', true );
@ini_set( 'display_errors', 0 );

// Use dev versions of core JS and CSS files (only needed if you are modifying these core files)
define( 'SCRIPT_DEBUG', true );

take only order here as well, use the getOrderId() I just committed

[captn3m0]

updateOrder should also be called with success=false for the error case?

Do a squash merge post testing.
