Summary Parsing of :nth-* pseudo-classes should accept strings starting with "+n"

E.g. "+n" or "+n+2" or "+n-2". Right now the tokenizer in CSSParser.cpp already accepts this (with a comment saying 'Simplest case. "+[0-9]*n" is always NthChild'), but the microparser in CSSSelector.cpp doesn't.

That’s not our best practice for regression tests.

WebKit appears to have separately added tests for nth-child(+n), which are passing, so I believe this is complete.
