tdf#158885 cui offapi sw xmloff: fix hyphenation at stem boundary
Add new hyphenation option "Compound characters at line end", equivalent of libhyphen's COMPOUNDLEFTHYPHENMIN, to limit bad pattern based hyphenation of compound words using morphological analysis of Hunspell. * Add checkbox to Text Flow in paragraph formatting dialog window * Store property in paragraph model: css::style::ParagraphProperties::ParaHyphenationCompoundMinLeadingChars * Add ODF import/export (loext:hyphenation-compound-remain-char-count) * Add ODF unit tests Note: slower Hunspell based hyphenation is used only if ParaHyphenationCompoundMinLeadingChars >= 3 (we assume that libhyphen hyphenation patterns cover the smaller distances correctly). Hunpell based hyphenation doesn't introduce new hyphenation breaks, only detects the stem boundaries from the libhyphen based hyphenation breaks. Follow-up to commit c899d3608d30f3ab4c2bc193c1fcd765221614a4 "tdf#158885 sw: don't hyphenate right after a stem boundary", replacing hyphenation zone dependence with the new "Compound characters at line end". Note: preset COMPOUNDLEFTHYPHENMIN values aren't loaded yet from hyphenation dictionaries. Note: the suffix of the last stem of the compound is always hyphenated, i.e. the distance limits only hyphenation inside the stem, not inside its suffix or at the end of the stem before the suffix.
