rst2odt:  remove page height and width

http://docutils.sourceforge.net/docs/user/odt.html

   5.10   Page size

   The default page size, in documents generated by odtwriter is Letter.
   You can change this (for example to A4) by using a custom stylesheet.
   See Defining and using a custom stylesheet for instructions on how to
   do this.

   On machines which support paperconf, odtwriter can insert the default
   page size for your locale. In order for this to work, the following
   conditions must be met:

      1. The program paperconf must be available on your system. odtwriter
      uses paperconf -s to obtain the paper size. See man paperconf for
      more information.

      2. The default page height and width must be removed from the
      styles.odt used to generate the document. A Python script
      rst2odt_prepstyles.py is distributed with odtwriter and is installed
      in the bin directory. You can remove the page height and width with
      something like the following:

         $ rst2odt_prepstyles.py styles.odt

pinpoint: fixing modeline

The vim modeline at the bottom of the presentation has an annoying
side-effect of creating a slide with the modeline text on it *only* when
generating a PDF.  Obviously a bug in the PDF processor, but since it's so
easy to work around, I'll go with that route.
