Justin Blank ac179cda7b Fix ReferenceError in compiler passes. 
Previously, the report-left-recursion and report-missing-rules passes
used PEG.GrammarError without requiring it, causing a ReferenceError.

Since requiring lib/peg.js would cause circular requirements, this
commit imports lib/grammar-error.js as GrammarError.

The bug was introduced in commit
4cda79951a.

Fixes GH-135.

David Majda 5e146fce38 Text nodes: Implement text nodes 
Implement a new syntax to extract matched strings from expressions. For
example, instead of:

  identifier = first:[a-zA-Z_] rest:[a-zA-Z0-9_]* { return first + rest.join(""); }

you can now just write:

  identifier = $([a-zA-Z_] [a-zA-Z0-9_]*)

This is useful mostly for "lexical" rules at the bottom of many
grammars.

Note that structured match results are still built for the expressions
prefixed by "$", they are just ignored. I plan to optimize this later
(sometime after the code generator rewrite).
