Update to inotify 0.2

[passcod]

With 0.1, we build. With 0.2, we don't:

   Compiling notify v2.5.4 (file:///home/code/rust/notify)
src/inotify/mod.rs:76:17: 76:21 error: cannot move out of borrowed content [E0507]
src/inotify/mod.rs:76         let _ = self.inotify.close();
                                      ^~~~
error: aborting due to previous error
Could not compile `notify`.

I think it makes sense that close takes ownership over the object, so that it can't be used anymore after this.
