refactoring with ResourceFetchMetadata
implemented deprecated window.timing functionality
created ResourceTimingListener trait
fixed w3c links in navigation timing
updated include.ini to run resource timing tests on ci
I moved away from the `Window` struct all the logic to handle task
sources, into a new struct called `TaskManager`. In a happy world, I'd
be able to just have there two functions, of the types:
```rust
fn task_source<T: TaskSource>(&self, name: TaskSourceName) -> Box<T>
fn task_source_with_canceller<T: TaskSource>(&self, name: TaskSourceName)
-> (Box<T>, TaskSourceCanceller)
```
And not so much duplicated code. However, because TaskSource can't be a
trait object (because it has generic type parameters), that's not
possible. Instead, I decided to reduce duplicated logic through macros.
For reasons[1], I have to pass both the name of the function with
canceller and the name of the function without, as I'm not able to
concatenate them in the macro itself. I could probably use
`concat_idents` to create both types already defined and reduce the
amount of arguments by one, but that macro is nightly only. At the same
time, not being able to declare macros inside `impl` forces me to pass
`self` as an argument.
All this makes this solution more verbose than it would be ideally. It
does reduce duplication, but it doesn't reduce the size of the file.

This will allow the HTMLMediaElement later to get a handle to the
RenderApi for rendering video frames.
At a later time, all media handling should be moved to its own
thread/process that is communicated with via IPC. At that point this
can be removed again.

Add task source name
Refactor `CommonScriptMsg::Task` to include `TaskSourceName`.
Sorry for the delay, between doing this after work and the time I spent trying to ramp up on the project, it took me a bit longer than I expected.
Test still don't pass in local, but they fail the same way on master, so I guess it's ok.
I may have forgotten something, I refactored mostly the stuff that the compiler complained about. Please let me know if I missed anything.
I tried to dump my thought process on the commit messages, so feel free to go commit by commit to understand context.
