Access to kovan governance/staking

[sakulstra]

Aave has contracts deployed for governance and staking on kovan. This allows:

• devs to preview their changes
• users to get familiar
  in a 0-cost environment

Right now the only way to access kovan staking/ governance is by checking out the repo and changing the config.
I think it would be nice to have a toggle on the ui, to switch between the two or similar.
