need support for newlines ending statements

[Maxwell Krohn]

Right now, we require trailing ';', as in C. But need to be more JS-like here. Unfortunately, this will deeply change the way we parse and manage the AST, so haven't really decided what to do next. Here are some thoughts:

• List of parsers here:
  • https://github.com/joyent/node/wiki/modules#parser-generators
• uglify / burrito?
  • https://github.com/mishoo/UglifyJS
  • https://github.com/substack/node-burrito
  • https://github.com/mishoo/UglifyJS/blob/6a873a7757895fdc06501854e4ba84e15c12a74a/tmp/instrument.js
