Improve Windows compatibility

[luislavena]

As Thor will be an important part of Rails 3, compatibility with Windows should be taken in consideration.

In the following gist you will find diff/patches to be applied over master that fix file operation and also increase the compatibility with Ruby 1.9.

On a side note, I noticed a lot of specs depends on successfully execution of previous one, making impossible ensure specs are doing what it suppose to (try executing with reverse options).

Cheers!

Thanks, merged. reverse order works with 1.8.7, not in 1.9.1. I really think this is a rr issue (their issues tracker says it haves problem with stubs on 1.8.7). I tried to fix, but I think I will simply migrate to another mocking solution.
