Choose address for swaps and buys

[trymeouteh]

Please add the ability to choose a address from your wallet (You can generate a new address or choose an address and see the addresses with their labels).

And be able to do this for return addresses in swaps (Such as in Monero) and for receiving addresses.

Simular to "Coin control in swaps & buy" but for having control over receiving addresses during a swap and buy. https://github.com/cypherstack/stack_wallet/issues/404
