v0.19.0 — EVM internal transactions

Added

• EVM internal transactions. ETH (and BNB, POL, …) that a contract sends —
  a withdrawal from a mixer or an exchange, ETH back from a DEX swap, a
  multisig payout — is now part of the native history, so trace, funder,
  victims, check and reports follow money through contracts. A wallet
  funded by a Tornado Cash withdrawal showed no funder before; now its funder
  is "Tornado Cash: 0.1 ETH".
• Keys from the Windows user environment. ETHERSCAN_API_KEY (and
  TRONSCAN_API_KEY) saved with SetEnvironmentVariable(..., "User") work in
  an already-open terminal.

Fixed

• Failed EVM transactions counted as transfers. A call that reverted moved
  nothing, but its value was booked as sent.
• Two Tornado Cash labels were wrong, checked against their own payouts:
  0x12d66f…b8fc pays out 0.1 ETH per withdrawal (was labelled 1 ETH), and
  0xd90e2f…f31b pays out 0.1, 1 and 10 ETH withdrawals — a router, not the
  0.1 ETH pool.

EVM native history stored by earlier versions is read again once, to pick up
the internal transactions.
