Jonathan Clark 69e902d085 tdf#162120 Implement style:writing-mode-automatic
Implements the ODF 1.2 paragraph attribute style:writing-mode-automatic,
and supporting runtime features. When set, this attribute allows
programs to automatically recompute the paragraph writing mode when the
contents of the paragraph have been edited.

The ODF standard does not suggest any particular algorithm for
automatically determining paragraph direction. This implementation uses
the rules from Unicode UAX #9 3.3.1.

Currently, LO will only automatically change the writing direction when
new text is typed or deleted. Other known interesting cases are already
tracked as separate enhancement requests.
