Rebase against upstream to have more features and potential fixes

[TimDaub]

Scope

E.g. wallet.leapdao.org doesn't have Address Book feature yet. So we'd like to take all progress from upstream

Gains

• Address book makes sending DAI much easier as you don't have to always confirm addresses when paying contributors
