Bug 1529606 - Add Copy Rule button to Changes panel. r=pbro Adds a button that shows up when hovering selectors in the Changes panel. When clicked, it invokes the same Copy Rule behavior implemented for the context menu: copies the full content of the rule with changes applied. The added/changed CSS class names use BEM notation. I intend to refactor the Changes panel stylesheet to BEM in a follow-up patch. Differential Revision: https://phabricator.services.mozilla.com/D20808

# tokio-executor

Task execution related traits and utilities.

[Documentation](https://tokio-rs.github.io/tokio/tokio_executor/)

## Overview

In the Tokio execution model, futures are lazy. When a future is created, no
work is performed. In order for the work defined by the future to happen, the
future must be submitted to an executor. A future that is submitted to an
executor is called a "task".

The executor is responsible for ensuring that [`Future::poll`] is called
whenever the task is [notified]. Notification happens when the internal state of
a task transitions from "not ready" to ready. For example, a socket might have
received data and a call to `read` will now be able to succeed.

This crate provides traits and utilities that are necessary for building an
executor, including:

* The [`Executor`] trait describes the API for spawning a future onto an
  executor.

* [`enter`] marks that the the current thread is entering an execution
  context. This prevents a second executor from accidentally starting from
  within the context of one that is already running.

* [`DefaultExecutor`] spawns tasks onto the default executor for the current
  context.

* [`Park`] abstracts over blocking and unblocking the current thread.
