v0.2.0-beta.4

This is a minor release that covers the things that we've done over the last week. Items in this release include:

• The beginnings of a proper CLI now exist:

npm install -g bitcore-node@0.2.0-beta.4
bitcore-node start

This will install bitcore-node and start the bitcore-node service. You can refer to the latest README for more information on the available commands for the bitcore-node CLI

• Shutdown behavior is vastly improved. When issuing a SIGINT (Ctrl-C), the bitcore-node service should exit cleanly.
• Unit tests have been expanded.
• Reorg behavior has been properly implemented.
• Wallet and RPC ready event handled in the bindings.
• Changes made so that BWS can be a module of bitcore-node.
