minor follow-ups to shesek's excellent changes:

- updated package-lock - include sample .env file for easy reference - continue to support key-by-key updating from credentials.js for now - minor code formatting - reflect status of BTCEXP_NO_RATES in UI when applicable (hide new exchanged-currency items from display dropdown and hide exchange rate on homepage) - rename _LOGIN to _BASIC_AUTH_PASSWORD for clarity - tweak README to call out .env-sample

 1. Clone this repo: `git clone https://github.com/janoside/btc-rpc-explorer`
 2. `npm install`
 3. `npm run build`
-4. Set environment variables with your bitcoind rpc credentials and other settings. See [configuration](#configuration).
+4. Configure via environment variables or `.env` file. See [configuration](#configuration).
 5. `npm start`
 6. Open [http://127.0.0.1:3002/](http://127.0.0.1:3002/)

 ### Configuration

-Configuration options may be passed as environment variables.
-You can also set them in a `.env` file in the root directory, in the following format:
-
-```
-BTCEXP_BITCOIND_HOST = localhost
-BTCEXP_BITCOIND_PORT = 8332
-BTCEXP_BITCOIND_USER = username
-BTCEXP_BITCOIND_PASS = password

-```
-
-You may enable password protection by setting `BTCEXP_LOGIN=<password>`.
-Authenticating is done with http basic auth, using the selected password and an empty (or any) username.
+Configuration options may be passed as environment variables or by creating a `.env` file in the root directory. See [.env-sample](.env-sample) for a list of the options and details for formatting `.env`.
