This commit introduces a websocket server via the --daemon argument.

```
./wowlet --daemon 127.0.0.1:1234 --daemon-password "sekrit"
```

The wallet will start in the background and expose a websocket port that you can connect to using a websocket client. This way, you will be able to control the wallet via websockets. The commands are defined in wsserver.cpp, in the `processBinaryMessage()` function.

- `openWallet` - opens a wallet by path/password.
- `closeWallet` - close current wallet.
- `addressList` - Returns a list of receive addresses.
- `sendTransaction` - Creates and sends a transaction.
- `createWallet` - Create a wallet by path/password.
- `transactionHistory` - Returns the complete list of transactions
- `addressBook` - Returns the complete list of address book entries.

Messages sent back and forth between the server and client are JSON. There is a Python example client available over at https://git.wownero.com/wownero/wowlet-ws-client
