Make media queries work with resize and page zoom.
gfx: Micro-optimize `DList` and `StackingContext` a bit.

I'm sad to say that this improved performance significantly. A lot of
this win is due to the Rust compiler not being smart about not zeroing
objects out if it doesn't need to.
Update web-platform-tests.
Support Back and forward button on mouses
Add serve-docs command to mach

This enables the user to run `./mach serve-docs` (with an optional port
number), starting a local web server that hosts the documentation for
Servo and Rust.

This closes #3807
auto merge of #3891 : Ms2ger/servo/wpt_20141103, r=jdm
Defer to GetAttribute in HasAttribute.

The semantics of has_attribute aren't anywhere close to the ones expected for
Element#hasAttribute, and it fails an assertion when passed non-lower-case
names.
Re-enable reflection-forms.html.
Pass an Atom to VirtualMethods::parse_plain_attribute.

Pass the correct argument to Element::create when cloning.

The current code calls as_slice() on the Option, yielding &[DOMString], and
then calls to_string, yielding "[prefix]".

The current code calls as_slice() on the Option, yielding &[DOMString], and
