Subject: Add video thumbnail, image viewer, video pause

    - Image can now be opened in the default viewer
    defined by the OS. Useful for cropped images.
    - Videos can have thumbnails now. We also
    resized them to be the same max width and height
    as pictures messages to avoid problems watching
    videos with absurd ratios.
    - Audio files can be paused now.
    - We got rid of the button for playing videos. You can
    now click on it for playing or pausing it.
    - You can now see any files attached to a message now.
    Outside the known formats displayed by kdeltachat (mp4, mp3,
    image files), the file name and a "Save attachment" button will
    be displayed. This button is not yet functional.
    - Filenames are now displayed in the label for attached audio, video
    and files. For example, a song named "naturesounds.mp3" will have
    "Audio - naturesounds.mp3" as the label
