Some packaging fixes:

- Add VERSION file, which contains just the version number of the release
- Add WHATSNEW, which is a short summary of the new release
- Add release.php which bumps all the necessary version numbers in files
- Update package.php so that the version numbers aren't hardcoded
- Add news entry for 1.7.0

The x subtag is now allowed in language codes. Element by element AllowedAttribute declaration is now possible for global attributes. Instead of *.class, you can write span.class. The old syntax still works, and enables the attribute for all elements.');
