GPG-error Update

Libgpg-error has been updated to the latest version 1.26. To correspond with this both libgcrypt and libssh have a new dash release which uses the updates to the newest gpg-error version dependency. As always the latest releases are available on the Projects page while still allowing access to any previously supported releases. The latest FFmpeg build has also been updated to use the latest versions of the new libraries as well.
