GCrypt, Game-music-emu and OpenSSL Updated

GCrypt has had a minor bug fix release and has been updated to version 1.7.5. Game-music-emu has been updated to 0.6.1 and OpenSSL was updated to 1.1.0c. As always the latest releases are available on the Projects page while still allowing access to any previously supported releases. No new FFmpeg build has been released as there is currently a compilation breaking error in the upstream repository that is preventing compilation with MSVC. Once this is resolved releases will continue as normal.
