Enable Hebrew spell checker after Jeremy fixed the underlying Webkit bug.

Related bug: http://code.google.com/p/chromium/issues/detail?id=2779
Related Webkit fix: http://trac.webkit.org/changeset/36874

Test:
Steps to repro:
1) open chrome, Hebrew UI
2) make sure the spell checker is on, and is set to Hebrew
3) type some Hebrew text in a RTL box (like RTL plain text finto), and use a
Hebrew word that the speller does not know.
4) type some more


Without the underlying Webkit fix:
the highlight marker is in a wrong location, and keeps moving while typing more
words after the unrecognized one.

With the underlying Webkit fix:
the highlight marker is in a correct and fixed location.
