Unity Bootstrap Tooling

The purpose of this tooling is to run through the initial deployment and configuration of the staking contract in order to bootstrap the creation of PoS blocks.

Note that this is really quick-and-dirty so just setup as an Eclipse project. In order to avoid requiring the building being done by everyone, I uploaded the built Tools.jar which includes the functionality here. If this becomes long-lived, we can generalize the build to make it a basic ant task so everyone can easily build and package it after making changes.

Description of relevant components:

1. Tools.jar - as mentioned, this includes the functionality of note which these scripts depend on. The main entry-points are cli.PackageJarAsHex which takes the JAR given as a path argument and returns it as a hex string and cli.SignTransaction which takes a private key and other data to produce the hex string containing the entire raw transaction.
2. registry.jar - the StakingRegistry smart contract. This is just the resource built from that project, committed here for convenience.
3. rpc.sh - adapted from the pre-node_test_harness functional test demonstration, this provides some of the lower-level logic around interacting with the JCON-RPC on the server as well as functionality from Tools.jar.
4. bootstrap.sh - the top-level script which takes no arguments and will synchronously perform all operations required to bootstrap PoS block production on a running PoW Unity cluster.

How to use this:

1. Ensure that the cluster is in a clean state (we depend on this being the first transaction that the premined account has sent).
2. Ensure that a node attached to the cluster is running, with JSON-RPC port open, on 127.0.0.1 (NOTE: The IP/host and port can be changed in rpc.sh).
3. Run ./bootstrap.sh and wait for it to complete (takes a minute since it requires at least 3 blocks to be mined).
4. Cluster is now bootstrapped and the premined account is now a valid staker.

What this does:

1. Deploys the StakingRegistry contract as the premined account.
2. Registers the premined account as a staker.
3. Votes 1 billion Wei (whatever we call the base unit on Aion) for the premined account, from the premined account.
4. Verifies that there is indeed 1 billion voted for the premined account.
