    note-obj: Fix html from text
    
    Application was replacing all "\n" character with a "<br/>" tab element,
    when creating html from text.
    
    This change fixes that, wrapping every text line up in a "<div></div>"
    pair tag element, taking care to not do that for the first line, which
    is the note title.
