Add combining, decomposition, digit, decimal, numeric methods to Ucd. Change lookup() to raise KeyError instead of LookupError. Remove expectedFailure markers from 9 passing tests. Add unicodedata.is_normalized() method. Rename decomp_chars to chars to fix spell check. Remove expectedFailure from test_named_unicode_escapes and test_urlsplit_normalization.
