Run a Parity node for development

Parity has a nice feature to run it as a private development chain (aka test RPC).

While testing it, I run into some problems, like:

• address management
• outdated genesis file
• the default configuration (--config dev) doesn't:
  • open up CORS
  • unlock the test keys

So here is my code to run Parity as a test RPC. It is designed to be as easy as:

npm install -g parity-dev
parity-dev
