    app: pack color picker and hexadecimal entry on same line in Color dock.
    
    There was no use to pack them on 2 lines. It was just making the FG/BG
    widget overly huge, and the color picker button and hex entry very long.
    This was just ugly. Also this dock is tall enough, so packing things
    horizontally when it makes sense is better.
