Before this commit, package.json in the project root directory was
preprocessed in order to insert correct version into it. This made it
invalid JSON and thus unusable for npm purposes.
This commit makes package.json a valid JSON by hardcoding the version
into it. I think that introducing this small duplicity is outweighted by
being able to use npm in project root directory. For example, it is now
possible to make the "npm test" command work and introduce Travis CI
integration.
This is the first of many commits that gradually convert PEG.js's test
suite from QUnit to Jasmine, cleaning it up on the way.
Main reason for the change is that Jasmine allows nested contexts,
allowing to structure the tests in a better way than QUnit. Moreover,
the tests needed to be cleaned up a bit.
