This trades quite a bit of complicated code in Servo for few more
messages and a significant performance improvement. In particular,
WebRender can search the entire display list at once instead of
ping-ponging down the pipeline tree. This allows us to send mouse
events to the correct pipeline immediately.
Make optional the usage of some unstable features
With `--no-default-features --features default-except-unstable`, more crates can now be compiled on stable Rust. This will help integrate them in rustc’s regression testing and compiler performance benchmarking.

"javascript:" urls: execute in correct global scope
<!-- Please describe your changes on the following line: -->
#### Summary
This pull request makes `javascript:` urls execute in the correct global scope.
#### Example
```html
<script> var x = 4; </script>
<!-- this branch: logs "4" -->
<!-- master: undefined variable error -->
<a href="javascript:console.log(x)">link</a>
```
#### Questions
I'm new to servo and rust, so I'm unsure about these changes. In particular:
* What's the appropriate place to evaluate the js?
* I moved it to `handle_navigate`, but I'm not sure if this will catch all occurrences of `javascript:` urls. I also don't know if this will execute in the correct thread and the correct window.
* What should I do with the result of the js evaluation?
* I just ignored it. The previous behavior displayed it as the content of a new page load.

- generalize the eval_js_url function so it can be called from
multiple places.
- call it in htmliframeelement.
- if the js eval results in a non-string result, then it won't
navigate to a new page, so don't block on the new page loading.
Problem:
After aborting on a 204 or 205 status code, you could no longer
follow links on the page.
Cause:
`constellation.rs` ignores new LoadUrl requests since the aborted
one is in its `pending_changes` list.
Solution:
Send a message to constellation that lets it clean up its
`pending_changes` list.

always call new_pipeline() before add_pending_changes()
There are some changes we want to make in `add_pending_changes` which require pipelines to be registered in self.pipelines.

I ran some tests at random from the `navigating-across-documents` folder, and they are passing.
