On Window node doesn't outputing as GUI program, so we have to switch to
chromium's implementation. Hacking into node (like what we did before
this commit) would sometimes make the outputing blocked.
Basic usage is:
remote = require 'remote'
Window = remote.require 'window'
w = new Window { width: 800, height: 600 }
Still need to do:
* Beter support for Array type.
* Remote objects should cheat devtools.
* Support cross-process callbacks.
