Update README to work with Bitcoin Core 0.16+ (#468)

Browse source 
The Bitcoin Core `addwitnessaddress` rpc command is deprecated in version 0.16.0. Thus, the example `bitcoin.conf` needs to be extended to with the option `deprecatedrpc=addwitnessaddress`.

Without this change, Eclair will not be able to open new channels and the following error message will be written to eclair.log: 

```
WARN akka.actor.OneForOneStrategy akka://default/user/$h/switchboard/peer-0390b6fbf04dd277955ce454c87b270d3c910fa96ef3d78afa4bf17d3b733fb877 - addwitnessaddress is deprecated and will be fully removed in v0.17. To use addwitnessaddress in v0.16, restart bitcoind with -deprecatedrpc=addwitnessaddress. Projects should transition to using the address_type argument of getnewaddress, or option -addresstype=[bech32|p2sh-segwit] instead. (code: -32)

Eclair will use any BTC it finds in the Bitcoin Core wallet to fund any channels you choose to open. Eclair will return BTC from closed channels to this wallet.
On **__testnet__**, you also need to make sure that all your UTXOs are `p2sh-of-p2wpkh`.
To do this, use the debug console, create a new address with `getnewaddress`, import it as a witness address with `addwitnessaddress`, and
send all your balance to this witness address.
If you need to create and send funds manually, don't forget to create and specify a witness address for the change output (this option is available on the GUI once you set the `Enable coin control features` wallet option).
On **__testnet__**, the addresstype of all your UTXOs needs to be `p2sh-of-p2wpkh`. This is the default addresstype starting with Bitcoin Core 0.16, which provides native segwit support. For earlier versions of Bitcoin Core, additional steps are necessary.
* for new wallets created with Bitcoin Core 0.16 or later, no additional steps are necessary.
* for existing wallets migrated to Bitcoin Core 0.16 or later, you need to create a new address and send all your funds to that address.
* if you are running Bitcoin 0.15.1 or earlier, you need to create a segwit address manually. To do this, use the debug console, create a new address with `getnewaddress`, import it as a witness address with `addwitnessaddress`, and send all your balance to this witness address. If you need to create and send funds manually, don't forget to create and specify a witness address for the change output (this option is available on the GUI once you set the `Enable coin control features` wallet option).
