Integrate additional reputation bootstrap mechanisms

[orishim]

Related to 117.

As we have seen with the launch of the dxDA, there are multiple ways to distribute initial reputation besides manually entering addresses, such as:

• Auction for Reputation
• [Hold Token Balance for Rep](https://github.com/daostack/arc/blob/master/contracts/schemes/ReputationFromToken.]
• Lock Token for Rep
• Lock ETH for Rep

In addition to or integrating into the Founders view, there should be support for these sorts of reputation bootstrapping mechanisms.
