http://www.robohornet.org gives a score of 101.36 on master, and 102.68 with this PR. The latter is slightly better, but probably within noise level. So it looks like this PR does not affect DOM performance.
This is expected since `Box::new` is defined as:
```rust
impl<T> Box<T> {
#[inline(always)]
pub fn new(x: T) -> Box<T> {
box x
}
}
```
With inlining, it should compile to the same as box syntax.

This removes six separate warnings when building servo. One of
the warnings was an unused mut, and the other were various dead code
warnings

This PR implements cross-thread `WindowProxy` objects.
At the moment, if a `Window` performs a non-similar-origin navigation, the old script thread does not update its `WindowProxy`, since the new `Window` is in the new script thread. With this PR, the `WindowProxy` is updated to a dummy `XOriginWindow` object, that only implements the whitelisted methods that are allowed to be called cross-origin.
This PR does not include working implementations of some of the cross-origin `Window` or `Location` methods.
This PR causes some cross-origin wpt tests to now pass, in particular `/html/browsers/origin/cross-origin-objects/cross-origin-objects.html ` now passes `Only whitelisted properties are accessible cross-origin`. There are some CORS failures in `fetch`, I suspect caused by the incorrect setting of `origin` in fetch requests.
Although there are some functions that now throw `SecurityException`, it is not meant to be a complete implementation, which will have to wait for XOWs to land.
