- configure electrumX servers with the same mechanisms as everything else
- include _PORT and _ELECTRUMX_SERVERS configs in .env-sample
- drop support for overriding configs via app/credentials.js, and use that filename for the new, dynamic, env-based credentials config file
This makes the protocol (either `tcp` or `tls`) for the electrum server
configurable, to allow communicating with an electrum server without tls
encryption.
- in tx history, request/display all inputs to get correct gain/loss values
- cross referencing for txid history from electrum
- include genesis coinbase values for genesis coinbase output address (electrum ignores the genesis coinbase TX and +50 value, but for consistency with the rest of this tool they're included)
- banner describing the electrum trust model
- ui tweaks including showing gain/loss for each address tx history item
