Recipients Section

[rauljareno]

For not having to scan or upload each time the QR code to send tokens, let's have a section that firstly show all the addresses that your account had interaction with in the past, and also that allow to save in the storage that address with some alias or contact info. This info will be encrypted in the app and never leave it. This way, next time the user needs to send tokens, we can show him a list of addresses used in the past and contacts to interact with, and keep allowing to scan a QR Code if still needed.
