Automatically run wallet listener

Convenience option, set to true by default in grin.toml, to
fork a wallet listener thread by default. Should make it easier
for people to get started on testnet2.

People who want to configure a password for their wallet seed,
run multiple listeners, change default address should set this
to false and manually configure and start their wallet listener.

This might break some tooling. Hopefully not.
