Refactor kredits related configuration in arapp.json

we use an environment specific entry for the daoAddress.
Locally we deploy our own, but for rinkeby and other public networks
we use the official entries.
To make deployments easy we store the address in the arapp.json

-`DAO_FACTORY` can optionally be set as environment variable. (see aragon)

+Configuration options can be set in an environment specific `kredits` object in the `arapp.json` or using a CLI parameter.
