This change moves the QSslSocket::supportsSsl() check from MetaParams:read() to main.cpp. This also ensures that the SSL check happens very early in Murmur's initialization process, rather than after we might have already attempted to call some SSL-related APIs. This change also moves the log message that prints the OpenSSL version to main.cpp, and integrates it with the QSslSocket::supportsSsl() check.
