Websocket refresh

[Corantin]

Right now we use interval pulling when we need some data to refresh, couple of problems with that :

• Poor performance
• More network usage
• Pulling is triggered only on current user actions (not other that might just add funds to a Quest)
  Implement a web socket to refresh some data on-demand :
• New quest should be put on top of the list after being created
• New claims and claims state update
• Quest Bounty update
