removed "window[class-name]" because this is not NodeJS compatible, and out code is already fast - we no longer need the Google Closure Compiler.
fixed call-python-callback/method tests.
added simple indentation to the javascript output, so it is more readable.
deprecated Python descriptors: __get__ and __set__
replaced by @property getters/setters and __getattr__
NodeJS: PythonJS is now compatible with NodeJS, added nodejs.py that takes in a python script and translates it to javascript, saves it to /tmp prepending the runtime.
NodeJS: properly detect if running inside NodeJS.
NodeJS: special nodejs import syntax and bindings to emulate python standard libraries: os, sys, io
first NodeJS test: nodejs/tests/file-io.py
