Fix Windows XP support on Visual Studio 2015+ (#439)
When compiling with Visual Studio 2015+, Crypto++ uses CryptoNG by
default. CryptoNG is only available on Windows Vista and later and
Crypto++ currently ignores if the user explicitly wants to target
Windows XP. Unlike with other Windows SDK features, everything
compiles, but the application doesn't start on Windows XP because
bcrypt.dll is missing. That is an issue when updating Visual Studio
because the root cause is hard to find.
Making use of CryptoNG when targeting Windows 8+ instead by default,
regardless of the Visual Studio version, to fix this.
