This branch updates node to 0.10.8, as well as updating its
dependencies. It also updates node-packages to use the new style
generated by npm2nix (some packages may have been lost in the switch,
please check!).
Note that 0.10 had some backwards-compatability breaks with 0.8,
particularly for readable streams. Please see the official documentation
for migration help.
Note that I have not yet tested this on darwin (node.js was already
broken there), but will do so soon and fix it if it's broken.
