SSL Support

It seems that WebRequest can't properly verify SSL certificates on Android and iOS, might be related to the Mono Version.

Most solutions I've seen online resume at doing the following:

ServicePointManager.ServerCertificateValidationCallback += (o, cert, chain, errors) => true;

Which works but is a terrible solution as it just removes all verifications.
So we need to either find a better HTTP client, or manually rewrite the ServerCertificateValidationCallback to implement a proper verification.
