* 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)

* 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

* 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?

* Remove titleOffset and add placeholder width for header nav buttons

* Remove passing `screen` prop for specific pages

* Use `-webkit-transform-origin-x: 0;` to have no padding on left side when scale font size smaller. See https://stackoverflow.com/questions/13031158/unwanted-left-margin-when-using-webkit-transform-scale

* Refactor code to only use `shortAddress` to determine whether to show full address on screen. `screen` prop not necessary

* Remove `-narrow` from Information and Name, only need it for Address component

* Increase scale to 0.95 so address just fits in on the tx summary page that uses the Unlock component

* Create TokenAddress similar to TokenBalance but doesn't need balance info from @withBalance

* 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

- Add option to import a Parity Signer account. It is then stored in
local storage.

- Send transactions with Parity Signer accounts

- Refactor sendStore so that "token" (and chainId) is inside this.tx;
avoids having to pass `token` around every function, and it makes sense
to put it in the object since it is part of the tx info.

- Add account type (either node or signer) to accountsInfo

- Add account type to withAccount; output props are now `{account:
{address, type}}` instead of `{accountAddress}`
