Include CJK UI Ext B in Pango

[Yao Zhang <yaoz nih gov>]

I find it remarkably simple to add CJK Unified Ideographs Extension B
support to Pango.  Only one line needs to be changed:

I have a TrueType font to test it with.  Everything works wonderfully.
You can find the screen shot, using my favorite excerpt as an example,
here:

Although most of the characters in CJK UI EB are rarely used, there
ARE a few of them being used very often: they were deliberately put
out of reach for too long :).  Now it is the time to unlock them by
adding CJK UI Extension B support into Pango.
