setup_federated_node improvements pre-docker

[robby-d]

• switch federated node to use ruinit scripts instead of upstart scripts
  • add autoupdate logic from git to counterpartyd startup script (e.g. on startup, before starting counterpartyd, IF we are running off of master, update from git master)
• add ability to run setup_federated_node.py non-interactively (by providing question answers via command line)
• add ability for setup_federated_node.py to set up to use pyrpcwallet instead of bitcoind
  • pyrpcwallet will need to be updated to use blockr/chain.so(?) and support testnet
