Initial implementation of using CAPI certificates with Schannel.
Introduced a new parent class for all certificates with keys (class CertificateWithKey is the new parent for PKCS12Certificate.) Switched to using "CertificateWithKey *" instead of "const CertificateWithKey&" Added calling of a Windows dialog for certificate selection when Schannel TLS implementation is used. This compiles, but is not tested. License: This patch is BSD-licensed, see Documentation/Licenses/BSD-simplified.txt for details.
