Update mac platform submodules.
Add CSS overflow property(hidden) test file
Add acid2 test case.
auto merge of #1250 : Ms2ger/servo/event-new, r=jdm
Add some more Blob methods/types
auto merge of #1267 : evilpie/servo/blob, r=jdm

I was going to add the Constructor overload, but that requires implementing that fallthrough case in CGCase, which I didn't feel like doing. At least we can compile the dict now.
Make the HTML parser parse into the document rather than an element.

This removes the duplicate html element.
auto merge of #1266 : Ms2ger/servo/double-root, r=jdm

This removes the duplicate html element.
Fix use of display().to_str in find_tests

Rewrite flow construction to be incrementalizable and parallelizable.

This replaces flow construction with a strict bottom-up tree traversal,
allowing for parallelism. Each step of the traversal creates a flow or
a `ConstructionItem`, similar to how Gecko works. {ib} splits are
handled by not creating `InlineFlow`s until the containing block is
reached.

This should be able to be incrementalized by storing the `Flow` from
layout to layout, and performing fixups during flow construction
and/or wiping containing blocks in a previous pass.

Following suggestion in the merge request, reuse the parameter passed to the
function that has the application name (so in future, if the browser no longer
is named 'servo', the code will continue to work fine).

auto merge of #1277 : Adenilson/servo/implementingHelp, r=pcwalton

Executing servo browser for the first time doesn't make evident that it already supports several different flags.

This patch implements a help message displaying the available options and a brief explanation on them, based on comments in source code (opts.rs).

I implemented both short hand/long hand options using getopts::groups.
