Adding debugging executable
Adding NodeJSGlobal constructors for tests.
Adding repl.js, readline.js, module.js and console.js node libraries (thinking that I should add node as a git submodule anytime soon).
Adding buffer.js and removing old mock.
Wiring process.stdout/stdin -> stream.stdout/stdin
Adding string_decoder.js for real.
Fixing broken test (adding Context as NodeJsGlobal parameter)
Making vm.createContext first parameter *truly* optional.
Adding native Buffer object mock.
Refactoring main to be simpler and adding stty goodies *-* (powered by node.js repl module)
Improving console IO primitives. Now when executing 'rhinodo' looks similar to node :)
