Import of short values of textDirection, used by OOXML strict

[Regina Henschel]

Hi Miklos, hi all,

I can fix bug 149556 by adding the missing values to
<resource name="ST_TextDirection" resource="List">
in core/writerfilter/source/ooxml/model.xml.
Is that really all to do? Or do I miss something?

If that is really all, it would be an Easyhack.

The issue is about the fact, that a short value 'lr' instead of the long 
value 'btLr', for example, is not interpreted.

Kind regards
Regina
