Subject: [PATCH] Disable send button after broadcast, show tx link and elapsed
 timer

Once a transaction is successfully broadcast: disable the send button
to prevent double-sends, immediately show an etherscan link for the
pending tx, and display a live elapsed-time counter that updates every
second until confirmation arrives.
