* Update Send transaction UI so "amount" field can be 0, since some users may want to just send some data (i.e. https://github.com/chainx-org/ChainX/issues/66)
* Set the default amount value to be 0 and not required
* Update Send transaction UI to support "data" field in hex (with 0x prefix)
* Use a hard-coded Gas Limit of 200,000 when user provides hex "data" value
* Remove logic that doesn't make sense (i.e. `else if (amountBn.isZero()) {`)
* Update validation messages
* Add support for Blockscout link when user using Goerli testnet
* Update internationalisation
* Use custom `isHexString` function instead of the ethereumjs-util's version. The ethereumjs-util's version is used by MyCrypto and doesn't work properly.
* Tested on Goerli testnet by creating two accounts, requesting Goerli tokens, running with `--chain goerli` appended to the end (i.e. `"start": "cross-env ELECTRON_START_URL=http://localhost:3000 electron-webpack dev --chain goerli",` in fether/packages/fether-electron/package.json), and sending a transaction with the high gas price, the hex data. For example, for ChainX convert your ChainX Address (UTF8 chars) into Hex code (i.e. copy/paste it at https://www.browserling.com/tools/utf8-to-hex, for example "helloworld" becomes => `\x68\x65\x6c\x6c\x6f\x20\x77\x6f\x72\x6c\x64`, and remove the `\x`, => `68656c6c6f20776f726c64` => then prepend 0x => `0x68656c6c6f20776f726c64` and add that to the "data" field), then send the transaction, and
when the transaction is successful go to the Blockscout link and you'll see under "Raw Input" ("Input Data" on Etherscan) that you can switch between viewing it in UTF8 or Hex, i.e. https://blockscout.com/eth/goerli/tx/0x7eaec61ce7753fd4c80aec4509c49942b53986585e4864e18134806bffb25f10/internal_transactions)

WIP - use craco in fether-react, and jest in fether-electron, as instructed, but tests still dont work

See https://github.com/paritytech/js-libs/pull/90#discussion_r

* Readme updated with environment variable prefix `TASKBAR=false` to disable taskbar.
Use existing "electron" and "start" scripts in package.json.
Configure taskbar to be enabled by default (i.e. `withTaskbar = true`)

* Integrate menubar functionality including for taskbar including:
    * electron dependencies: `Tray`
    * electron-positioner: `Positioner`

* Separate logic in `FetherApp` component dependending on whether `withTaskbar` is enabled,
but shared functionality in `finalise()` function

* Incorporate relevant Pino logs throughout to improve developer experience

* Move options into FetherAppOptions class and move configuration config for options into
a config subfolder within the module.

* Use `extends` library to overwrite `DEFAULT_OPTIONS` options properties with those in `TASKBAR_OPTIONS`
if `withTaskbar` is enabled

* Add ability to pass `customOptions` to further overwrite the values in the config directory, and add option setter and getters

* Move taskbar icons into app/options/config subdirectory.
Use different logic to set the path of the icons directory depending on whether it was run
using the "electron" or the "start" script in package.json. Leverage the fact that when
"electron" is run the environment variable `SKIP_PREFLIGHT_CHECK=true` is set

* Set the Electron option `webPreferences.devTools` depending on whether we are in production or not
particularly for security reasons

* Fix `activate` event listener to cater for `withTaskbar` enabled or disabled usage

* BUG: When running with `withTaskbar` enabled we are setting the option `show: false`
because it opens the window in the center of the screen instead of positioned right under the
taskbar icon at the top of the screen.
When you click the icon in the taskbar it toggles the window open/close correctly positioned
since it takes into consideration the `bounds` value in `FetherApp.clickedTray`.
To fix the bug we need to reuse the same approach.

* BUG: Additional `EventEmitter` does not appear to be working correctly or is not required.
Investigate if can remove

* Remove TypeScript types (we're not using TypeScript here!)

* Add Babel.js to fether-electron package similar to fether-ui

* Change to block `onProgress: progress => {` otherwise it doesn't compile

* Use https://babeljs.io/docs/en/next/babel-plugin-proposal-class-properties.html
