Disable -ffast-math in release builds, as it was causing problems.
Added a build config that disables a number of things that might trigger antivirus FALSE-positives (including all http+tcp support, process forking, tls/crypto), for use in SDL builds where any further system interactions is deferred to SDL. For crippled builds.
Made the output of the version command more verbose to reflect networking features.
