* Change health states to node-internet, node, and sync

* Change from using STATUS symbol states to using a status object that contains the different states with their status

* Show chain name and percentage in modals too

Summary of actions performed:

* App.js routes
	* AccountsList
		* New functionality - `<RequireHealthOverlay require='connected-offline'>`
			* Note: we need to be connected even for the AccountsList page since most accounts actually come from parity-ethereum (as pointed out by @amaurymartiny). New functionality (@amaurymartiny proposal) uses additional 'connected-offline' state so if we are connected to the node but not to the internet we can show the AccountsList page
	* Accounts (token list page)
		* Retain existing functionality - `<RequireHealthOverlay require='sync'>`
	* Create Account / Import Account
		* New functionality - `<RequireHealthOverlay require='connected-offline'>`
	* Backup Account
		* New functionality - `<RequireHealthOverlay require='connected-offline'>`
	* Onboarding
		* New functionality - no overlay since not wrapping App.js
	* Search tokens (Whitelist)
		* Retain existing functionality - `<RequireHealthOverlay require='sync'>`
* Send.js routes
	* TxForm, Unlock, TxQrCode, ScanSignedTx, SignedTxSummary
		* Retain existing functionality - `<RequireHealthOverlay require='sync'>`
	* Sent
		* Retain existing functionality by wrapping the individual component instead of App.js with: `<RequireHealthOverlay require='connected' fullscreen>`

* Note: `RequireHealthOverlay` has two states:
		* `require='connected-offline` no alert/overlay when user connected to a local node but not connected to the internet
		* `require='connected'` shows full screen alert when the user is not connected to the node and and not connected to the internet
		* `require='sync'` shows when the user is not sync
* Note: Only the Sent component has a fullscreen overlay
* Note: This wraps everything related to eth/token/balance/transfer with `require='sync'`
* Note: We are not wrapping App.js anymore since when using both `<RequireHealthOverlay require='connected' fullscreen>` in addition to wrapping other components such as Accounts.js with `<RequireHealthOverlay require='connected-offline'>` doesn't allow it. Instead just wrap individual components

review-fix: Remove value from To since already initialValue. Modify existing initialValue for Amount

review-fix: Use react-final-form field to connect to state. Change from defaultValue to value to overcome warning

fix: Fixes #398. Remove withoutLoading() from withAccount so no blank screen changing to Account page during sync or offline

https://github.com/paritytech/fether/issues/398

fix: Fix SignedTxSummary page for Parity Signer tx so it shows amount field similar to on Unlock summary for non-Signer tx

* `account_name -header` CSS is actually only required where Name is used in the Account Header,
elsewhere we do not want to add top and bottom padding to the Name component.

* Remove `decimals`, `onClick`, and `tokens` props from TokenAddress as was only required
on TokenBalance

* Update SignedTxSummary so "To" input field is above "Amount"

* Explicitely pass down `drawers` prop since it is used by Card component

* Remove incorrect `handleClick` from TokenAddress component, as
that was functionality from TokenBalance

refactor: Rename handleMenuOpen to onOpen and same to close. Remove unnecesary isMenuOpen from child

for good measure

Might fix https://github.com/paritytech/fether/issues/379
Previously, we would resolve the promise and then set `this.txStatus`. However, resolving the promise actually redirects to `Sent` which expects `txStatus` to already be defined

See https://github.com/sharegate/craco/issues/61.
Updating to craco 3.3.1 resolves error when trying to install dependencies and build:
```
Error: Cannot find module '~/code/src/paritytech/fether/node_modules/react-scripts/config/webpack.config.dev'
```

* Remove useless .header-container

* Add width to .account_information to fit full title width

* Use `flex-grow` instead of abbreviation `flex`

* Use justify-content: left to align account info and avatar to left and remove flex: 0 from .header-tokens

* Remove titleOffset and add placeholder width for header nav buttons

* Remove passing `screen` prop for specific pages

* Change Account screen so its header uses the Information component with a big identicon, a short address,
so it is clickable, and with identicon on left of name and address.

* Apply extra bottom margin between name and account address when Information component used in the header

* Update header so it uses Flexbox according to docs as intended

* Since we're using Flexbox without placeholder spacing for the left and right header buttons, when the title
is shown in the header it is offset if there is only a left or right button. So a `titleOffset` prop
is used on pages where the Header component is used to indicate if the title needs to be offset to the left
or right so it appears centered in the screen. We also pass a `screen` prop (named after the component where the
Header component is being used so we can tailor the header spacing on specific screens.

* Re-order props alphabetically

* QUESTION - should we consider always adding placeholder spacing for where both right and left buttons in header would be as an alternative so no offset for the title is require?
