Parsing crashes on game with {...} indicating incomplete move log

[atduskgreg]

The following PGN appears in the http://chessgames.com archive of games played in 2014:

[Event "Bunratty Masters"]

Trying to parse this with PGN raises the following error:

Whittle::UnconsumedInputError: Unmatched input "{...}\n1-0" on line 19
    from /Users/greg/.rvm/gems/ruby-1.9.3-p362/gems/whittle-0.0.8/lib/whittle/parser.rb:251:in `block in lex'

    from /Users/greg/.rvm/rubies/ruby-1.9.3-p362/bin/irb:16:in `<main>'    

I think that "{...}" is meant to indicate an incomplete move log. Even though it doesn't appear in any PGN documentation that I can find. Not sure what the best policy in parsing is here, however the current result where I'm PGN crashes midway through parsing this archive of ~10,000 games and forces me to write code that splits up the games myself with a regex and iterates over the resulting strings in order to pass them one-by-one into PGN to rescue just the one that crashes is probably not the optimal situation.

I've added support for comments in my fork (see #3), can you test there?
