David Majda 2d38c5cab3 Handle non-unique expected values of match failuers differently
Before this commit, uniqueness was checked when addding the failure. Now
we make the entiries unique when generating the error report, saving a
little time when the parsing is successful. This does not increase the
benchmark numbers too much though.

David Majda 7b03f164b8 Avoid passing |context| in the generated parser
Passing the context is not necessary, global variable is good enough
(passing the context would make more sense if each AST node was
translated into a function call, but this isn't the case).

The performance gain is very small, on the border of statstical error.

David Majda e59f3ba338 Split the source code into several files, introduce build system
The source code is now in the src directory. The library needs to be
built using "rake", which creates the lib/peg.js file by combining the
source files.
