Return success on sucessful domain renewal/restore

[DennisSkov]

When a domain renewal is successful, it's required to return 'success' => true, otherwise WHMCS doesn't send the admin email template "Domain Renewal Successful".

When a domain needs to be restored, it's not done automatically; you have to access OpenProvider. Ideally, there should be a field in WHMCS to enable or disable automatic restoration.

I don't think that's necessary. WHMCS already supports domains in redemption period - and you can even sync the redemption details (days until grace/redemption and price) from the registrar. There's no reason not to restore domains automatically.

If the domain has "Redemption" status in WHMCS, that means an admin setup redemption settings for the TLD.
WHMCS won't put domains into redemption status unless it has been manually configured for the specific TLD - if it hasn't, it's just set to "Expired".
Basically, if both OpenProvider and WHMCS returns that the domain is in redemption, you restore the domain. If the two statuses doesn't match, you throw an exception instead.
