sw: read theme from OOXML file and set it to the draw page

This change extends writerfilter to use oox::ThemeFragmentHandler
to read the theme properties, and sets that to the one and only
draw page of a Writer document.

This change also removes ThemeTable and replaces it with the
ThemeHandler, which takes theme font data from svx::Theme
instead.

In addition, a test has been writen, which loads a document with
a theme, and asserts the draw page has the theme and the theme
properties currently supported.
