Indicate confirming bounties not possible without connected wallet

[tpatja]

User Story

As a user, I want to have a clear indication that confirming bounty payouts is not possible unless I have an Ethereum wallet connected to the app.

Description

Type: Improvement

Summary: Currently the manage bounties view shows a greyed out "Confirm" button for bounties pending payout if the signed in used has no Ethereum wallet connected.

Solution

Let's add a warning style message (something like http://semantic-ui.com/collections/message.html#warning) to top of the view with the text "To sign claims, please view Commiteth in Status, Mist or Metamask".
