Address book

[MrStahlfelge]

In addition to pasting and scanning addresses, an addressbook should be added for users to pick addresses from to send funds. This address book should always show own wallet addresses, but can be filled with own ones either manually or by selecting an address from a transaction (so to be done not before #13 )

When an address is known, send screen and transaction list should show the given name from the address book.
