[Plugin] Http/s REST, blueprintable JSON and Parse REST API manager at once (VaRest)

When I toggle the Verify Peer setting in the Project Settings, I get “LogInit: Warning: CVar named ‘n.VerifyPeer’ marked up in NetworkSettings was not found or is set to read-only”, and the setting has no effect. I tried going the C++ way but I can’t figure out which header to include to get FCurlHttpRequest. I can’t find it in the UE4 API documentation either. Halp!
