    Add command-line option to ignore comments
    
    With '-i' or '--ignore-comments', pinpoint will not show comments.
    
    This is useful when you have to present a PDF version on a machine
    without pinpoint (of which there are a shocking number).  The default
    PDF output includes the comments as notes on interstitial pages, which
    breaks up the flow and is possibly embarrassing.
    
    It is also possible to use -i in speaker mode, in the strange case
    that you want to see imminent slides and the time but not your notes.
