tdf#149324 sw offapi xmloff: add option to not hyphenate short words

Add paragraph property to disable automatic hyphenation of short
words based on a minimum character count.

Note: there is a (broken) global option for Minimum Word Length
at hyphenation, see "Minimal number of characters for hyphenation"
in Tools->Options->Language Settings->Writing Aids), but
for better/comfortable paragraph-level adjustment of typesetting,
add a paragraph property for it. The same option is available e.g.
in Adobe InDesign and in CSS Text Module Level 4 (hyphenate-limit-chars).

* Add checkbox to Text Flow in paragraph dialog
* Store property in paragraph model (com::sun::star::style::ParagraphProperties::ParaHyphenationMinWordLength)
* Add ODF import/export
* Add ODF unit test
* Add layout test
