Add self-referential resolvers and ABIs to deployed contracts

[Arachnid]

For commonly deployed registrars -.eth, .test, .addr.reverse etc - we should set resolvers for each of these, and configure them to resolve to their owners. This permits simple lookup of a registrar's address by entering the TLD, rather than having to look up that node's owner.

We should also deploy ABIs to each of these, as well as for the public resolver.
