* Add support for one-click onboarding
MetaMask now allows sites to register as onboarding the user, so that
the user is redirected back to the initiating site after onboarding.
This is accomplished through the use of the `metamask-onboarding`
library and the MetaMask forwarder.
At the end of onboarding, a 'snackbar'-stype component will explain to the
user they are about to be moved back to the originating dapp, and it will
show the origin of that dapp. This is intended to help prevent phishing
attempts, as it highlights that a redirect is taking place to an untrusted
third party.
If the onboarding initiator tab is closed when onboarding is finished,
the user is redirected to the onboarding originator as a fallback.
Closes#6161
* Add onboarding button to contract test dapp
The `contract-test` dapp (run with `yarn dapp`, used in e2e tests) now
uses a `Connect` button instead of connecting automatically. This
button also serves as an onboarding button when a MetaMask installation
is not detected.
* Add new static server for test dapp
The `static-server` library we were using for the `contract-test` dapp
didn't allow referencing files outside the server root. This should
have been possible to work around using symlinks, but there was a bug
that resulted in symlinks crashing the server.
Instead it has been replaced with a simple static file server that
will serve paths starting with `node_modules` from the project root.
This will be useful in testing the onboarding library without vendoring
it.
* Add `@metamask/onboarding` and `@metamask/forwarder`
Both libraries used to test onboarding are now included as dev
dependencies, to help with testing. A few convenience scripts
were added to help with this (`yarn forwarder` and `yarn dapp-forwarder`)
The component has been updated to split the container from the base
component, and all hyperscript has been replaced with JSX. ES6 imports
are used throughout as well.
The units for the amounts shown on the approve screen in the
transaction fee section were missing. It appears that they were present
in an early version of the approve screen (#7271) but they got lost
somewhere along the way.

Maker has upgraded its Dai token to "Multi-Collateral Dai" (MCD) and requires
all users interacting with Dai migrate their tokens to the new version. Dai
now exclusively refers to Multi-Collateral Dai and what was previouly called
Dai is now Sai (Single Collateral Dai).
In this description, Sai refers to what was (prior to the 2019-11-18) known as Dai.
Dai is the _new_ token.
This changeset:
1. Only affects users who had non-zero Sai at the old contract address
2. Displays a persistent notification for users with Sai
3. Updates the token symbol for users already tracking the Sai token
4. Bumps our direct and indirect eth-contract-metadata dependencies
The notification copy:
> A message from Maker: The new Multi-Collateral Dai token has been released. Your old tokens are now called Sai. Please upgrade your Sai tokens to the new Dai.
The copy is from the Maker team.
