Povilas Kanapickas a428b61c7d gui: Add support for SHA256 fingerprints
For the time being both SHA1 and SHA256 fingerprints will be shown in
the UI. This allows users to verify new connections between old and new
versions of Barrier. After the initial verification we use SHA256
fingerprints.

The issue has been reported by Matthias Gerstner <mgerstner@suse.de>.
