UCD 5.0: Apply Unicode Corrigendum #6

http://unicode.org/versions/corrigendum6.html:
> in Unicode 5.0, the list of characters with the Bidi_Mirrored property
> was made consistent for brackets and quotation marks, in preparation for
> new constraints on bidi mirroring. However, after publication of
> Unicode 5.0.0 it was discovered that this change adversely affected
> several quotation mark characters in deployed data.
