    Run dialog: don't keep duplicate commands in history

    The run dialog should only show unique commands. This makes the run
    dialog significantly more useful as a quick launcher for regularly used
    commands. History deduplication matches the behaviour of e.g. gmrun or
    the the venerable Metacity/MATE run dialog.

    Technically, if recalling a previously used command from history, the
    command will be appended as most recent item to the history and all
    earlier occurrences will be removed.

    This patch also provides a smooth upgrade path for existing histories.
    The history is initially left untouched, but once a previous command is
    recalled, all duplicates are removed.
