Copying assets doesn't work on windows

[dignifiedquire]

I've tried to use codo under windows 7 (64bit) but the copying of the assets won't work. It just creates empty css and js files.

I've been able to fix it by replacing

to.once 'open', (fd) -> require('util').pump from, to

with

from.pipe(to)

in the method copy in generator.coffee

Thanks for the issue and the Windows fix. 0.9.1 is released that contains your changes.
