Add Hyphenation Support to AbiWord

by chenxiajian for AbiWord

AbiWord currently does not support automatic hyphenation. Hyphenation programs used in computerized typesetting employ varied techniques often in combination to determine where to break the last word on a line. Usually, a dictionary lookup procedure is combined with a "logical hyphenation program" which bases its decisions on the recognitionof certain characters, strings of characters, or patterns of vowels and consonants. And I try to Integrate the 'hunspell' dictionaries for hyphenation.
