hw_device: support for multiple devices added [for review]

- device name is a new wallet property
- full device name is now a bit more structured so we can address particular device vendor + device path. Example: 'Ledger', 'Trezor:udp', 'Trezor:udp:127.0.0.1:21324', 'Trezor:bridge:usb01'. The part before ':' identifies HW device implementation, the optional part after ':' is device path to look for.
- new --hw-device parameter added to the wallet, can name the hardware device
- device reconnect added
