RTF/DOCX export: always set hyphenation to auto at document level

MS formats unlike ODT have also global setting for hyphenation
params. Previous approach was to set this global value depending
on default paragraph style settings. However, if hyphenation is
enabled ony for specific other paragraphs, hyphenation in MS Word
will not work.

Let's try to set global hyphenation value to "auto" and explicitly
enable/disable hyphenation on paragraph level.
