Create Address settings page

[ohld]

In this page a user should see:

1. Public address (or at least some first and some last symbols)
2. QR code with it (*)
3. Balance
4. The time of last sync

Have buttons:

1. Sync address
2. Add this address to Apple Wallet (not sure, should be discussed and tested)
3. Share address (*) - it generates the link to https://flightwallet.org/pay and allows to send it somewhere.
4. Copy address

Should be able to

1. Set color for address
2. Set short address description
3. Mainnet-testnet select button

(*) We definitely need to share address with Amount. I don't know now where we should have the input field for Amount value.
