Multiple masternode address setup and collateral send

setup.py

#!/usr/bin/python

# usage:
# ensure wallet config has these items without the # prefix, restart the wallet
# if they need to be added to the config:
#
# server=1
# rpcuser=anrpcusername
# rpcpassword=apassword
#
# ./setup.py <host:port> <rpcuser> <rpcpassword> <collateral> <count> <startindex>

# e.g., to setup 10 nodes starting at mn-6
# ./setup.py 127.0.0.1:13512 user pass 1000 10 6

# output of masternode key and transaction id will be in transactions.txt in the form
# MN-<number> ip:port <privkey> <transaction id>
# NOTE: you will need to add the ip:portand the tx output index to each line, then merge it into your masternode.conf file

# pip install python-bitcoinrpc
