Feature: add avatar, message to world and twitter link when creating account

[TonioMacaronio]

Current behavior:
Now you can only register account with name.

Expected behavior:
Need to register account with:

• avatar
• website
• location
• message to world
• twitter link
• info

Data needs to be sent both to PeepEth server and to blockchain.

Solution:
It’s needed to prepare sending data to server and to Ethereum blockchain.
Carefully look at how account registers now.
Perhaps for avatar you need just to load image to some server and use its link when forming registration data.

Registration for new account starts in SettingsViewController.
You form user data:

let user = User(info: "",
                location: "",
                realName: realName,
                website: "",
                avatarUrl: "",
                backgroundUrl: "",
                messageToWorld: "",
                untrustedTimestamp: timeStamp)

As you can see there are a lot of empty values. Fill them

To get more info about how does it works - register account from Desktop PeepEth in Chrome using Developer Tools to “reverse engineer it”.

Acceptance Criteria:
