* 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

fix: Fixes Cannot read getGlobal of undefined since remote must be enabled in fether-electron config to use fether-react

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

* Update tests to include missing `token` property to a Tx of Ether or Token

* Update tests to include missing `address` property to a Tx of Ether to fixes `TypeError: Cannot read property 'address' of undefined` error

* Update tests to include missing `options` and `args` properties to the Tx so the second argument passed to `transfer$` in `contractForToken(token.address).transfer$(..., ...)` is not NaN

* Fix error `ReferenceError: regeneratorRuntime is not defined`

* Fixes `SyntaxError ... Decorators transform is necessary.` (regarding use of `@observable`)
* Fixes `Decorating class property failed. Please ensure that proposal-class-properties is enabled and set to use loose mode. To use proposal-class-properties in spec mode with decorators, wait for the next major version of decorators in stage 2.`
