[simple-scan/wjt/improve-description] data: improve .desktop comment and appdata description

    data: improve .desktop comment and appdata description
    
    The description for the 'Comment' key in the Desktop Entry Specification
    says:
    
    > Tooltip for the entry, for example "View sites on the Internet". The
    > value should not be redundant with the values of Name and GenericName.
    
    The appstream specification has this to say about <summary/>:
    
    > A short summary of what this component does. If the component is
    > "PackageKit", the summary could be "Provides a package-management
    > abstraction layer".
    
    "Scan Documents" seems redundant with "Document Scanner"; this string
    better describes what the application does.
