Title: Add and use VeriSign and DigiCert root certs

This commit adds VeriSign and DigiCert root certificates and overrides the **hoauth** defaults so that **libcurl** will actually verify Twitter certs. (Otherwise **Network.OAuth.Http.CurlHttpClient** turns off `CurlSSLVerifyPeer` by default...)

I may spend some additional time playing with a proxy, but didn't want to delay a fix.

Note: I suspect that on MacOS we may need some additional gymnastics to locate the cert files, so somebody should give it a try and let me know.
