    lisp/ox-latex: Omit empty date
    
    * lisp/ox-latex.el: (org-latex-template): When no date is provided or
    the export option date is nil, the empty '\date{}' string is no
    longer included in the exported latex document.
    
    The default behaviour for ox-latex was to include an empty date line as
    '\date{}'.  This empty date line can affect more complex latex templates
    when the date is for example set by the template on compilation, or when
    the date command is overwritten entirely.  In this new patch, the date
    line is omitted from the exported document.
