Removed Step 30.2 which raised a JS TypeError if the integrity metadata was not empty. I manually ran `new Request("", {"mode" : "no-cors", "integrity" : "not an empty string"});` in servo to validate that the exception no longer arose.

Problems:
* the Heap::new constructor is memory-unsafe with any value other than Undefined/Null
* this means that moving dictionaries containing Heap values (ie. any/object) is memory-unsafe
* unions containing GC pointers are similarly unsafe
Solutions:
- dictionaries containing GC pointers are now wrapped in RootedTraceableBox (even inside other dictionaries)
- instead of using Heap::new, dictionaries containing GC pointers are now initialized to a default value (by deriving Default) and mutated one field at a time
- dictionaries containing GC pointers are marked #[must_root]
- FromJSVal for dictionaries containing GC pointers now returns RootedTraceableBox<Dictionary>
- unions wrap their variants that require rooting in RootedTraceableBox
Rather than attempting to derive Default for all dictionaries, we only do so for the dictionaries that require it. Because some dictionaries that require it inherit from dictionaries that do not, we need to write manual implementations for those parent dictionaries. This is a better option than having to figure out a default value for types like `Root<T>`, which would be required for deriving Default for all dictionaries.
I would still like to come up with an automated test for this, but I figured I would get eyes on this first.

<!-- Please describe your changes on the following line: -->
The README currently points to a 2 year old version python for windows (2.7.11). While this version works for servo development, builds also work with the current version (2.7.14), so the link can be updated.

Because nsAString is nicer to work with than char16_t*. The patch relatedly
changes nsIEmbeddingSiteWindow::title and nsIWindowMediator::updateWindowTitle
as well.

The removed tags don't need a separate check because nsHTMLElement::IsBlock()
will return true for them.
