Integrate additional reputation bootstrap mechanisms

Related to [117](https://github.com/dOrgTech/DAOcreator/issues/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](https://github.com/daostack/arc/blob/master/contracts/schemes/Auction4Reputation.sol)
- [Hold Token Balance for Rep](https://github.com/daostack/arc/blob/master/contracts/schemes/ReputationFromToken.]
- [Lock Token for Rep](https://github.com/daostack/arc/blob/master/contracts/schemes/LockingToken4Reputation.sol)
- [Lock ETH for Rep](https://github.com/daostack/arc/blob/master/contracts/schemes/LockingEth4Reputation.sol)

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