bump crengine: word spacing and hyphenation tweaks

Includes:
- New option to tune word spacing: space width scale percent
- Text: look for hyphenation in more words if needed
- CSS: fix "hyphens:none" should override inherited "hyphens:auto"
- getHtml(): grab dir= and lang= attributes from upper nodes

Replace our Word Gap/Space condensing toggle/setting with
a new Word Spacing toggle/setting, made of 2 values:
- 1st number scales the normal width of spaces in all font
  (100% uses the font space width untouched)
- 2nd number applies after the 1st has been applied, and
  tells how much these spaces can additionally be condensed
  to make more text fit on a line.
