QCharAttributes: add wordStart/wordEnd flags
A simple heuristic is used to detect the word beginning and ending by
looking at the word break property value of surrounding characters.
This behaves better than the white-spaces based implementation used before
and makes it possible to tailor the default algorithm for complex scripts.
BIG FAT WARNING: The QCharAttributes buffer now has to have a length
of string length + 1 for the flags at end of text.
