Working on node-0.11.x

this was a pretty hefty conversion, but all the tests are passing. it builds and runs on:
 - node-0.11.11 (with the windows bit removed from node.h)
 - node-0.10.25 (stable)
 - node-webkit-0.8.4

I also did some maintenance in the second commit. feel free to ignore it.

few things to note:
 - I removed support for node-0.1.x but I don't think anyone is using it anyway
 - some tests need to be written for getters/setters on integer indexes (arrays). I have code that uses it, so I'll eventually know for sure if it's working or not
 - I know this is kind of silly because harmony proxies are better and faster (but not on by default), and since I use this library as a fallover (sorta like gnode) I wanted it working..

cheers!
