Handle derived names for CJK Ideographs, Hangul Syllables, etc.

[OtterSou]

There are some characters whose names are derived from codepoints or other sources.
(See Section 4-8 and specifically Table 4-8 in the Unicode Core Specification)

Your website seems to use values from UnicodeData.txt directly, so it shows "<CJK Ideograph, First>" instead of "CJK UNIFIED IDEOGRAPH-4E00"

I don't have time to fix this right now, but thank you for pointing it out. Send a patch if you want and I'll take a look.
